SRV05-4

1N4001 is an onsemi standard rectifier diode — VRRM 50 V, 1 A average rectified current, DO-41 axial package. The 1N400x family is the selection point: the cheapest diode on earth for mains-frequency rectification and reverse-polarity protection — a jellybean part every lab stocks by the thousand. Selection advice: the 1N4001 is the 50 V bottom grade of the 1N4001–1N4007 family (50 V to 1000 V, same DO-41 package) — for mains work always specify the 1N4007 (1000 V); the 1N4001 suits low-voltage rails only. For switching supplies above a few kHz use a fast-recovery type instead — standard recovery overheats at high frequency. onsemi lists the 1N4001 as Active. Evidence: distributor data confirms onsemi 1N4001 Active, 50 V, 1 A, DO-41. Match the full 1N4001 code — siblings look identical. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

1N4002 is a 1 A standard-recovery rectifier diode from the 1N400x family — 100 V repetitive peak reverse voltage, 1 A average forward current, 30 A surge capability, axial DO-41 (DO-204AL) package, 1.1 V maximum forward voltage, -65 to +150 °C. The 100 V rating is the selection point: the economical choice for low-voltage rectifiers, relay flyback clamps and reverse-polarity protection where high blocking voltage is unnecessary. Selection advice: pick the voltage grade to match your peak reverse voltage with margin — 1N4004 (400 V) or 1N4007 (1000 V) are the higher-voltage neighbors in the same DO-41 footprint. For switching supplies use an ultrafast type like UF5408 instead, since this is a standard-recovery part. Evidence: Vishay 1N4001–1N4007 datasheet confirms 1 A, 100 V, 30 A surge, DO-41 and 1.1 V forward voltage. Match the full 1N4002 code — the digit sets the voltage rating. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

1N4003 is a general-purpose 1 A rectifier diode in DO-41 — 200 V repetitive peak reverse voltage, 1 A average rectified current, 30 A non-repetitive surge, 1.1 V maximum forward voltage at 1 A, 5 µA reverse leakage, -65 to +150 °C, through-hole axial. The 200 V rating is the selection point: the mid-voltage member of the 1N400x family — choose this grade when your circuit never sees more than 200 V, and step up to the 1N4007 for higher-voltage margins. Selection advice: standard recovery (>500 ns) suits mains-frequency rectification only, not fast switching — use an ultrafast diode for switch-mode outputs. The silver band marks the cathode. Evidence: manufacturer datasheets and distributor listings confirm 200 V, 1 A, 30 A surge and DO-41. Match the full 1N4003 code for voltage grade. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

1N4004 is a 1 A standard-recovery rectifier diode from the 1N400x family — 400 V repetitive peak reverse voltage, 1 A average forward current, 30 A surge capability, axial DO-41 (DO-204AL) package, 1.1 V maximum forward voltage, -65 to +150 °C. The 400 V rating is the selection point: the sweet spot for rectified 230 VAC mains with margin and for general-purpose rectification, relay flyback clamps and reverse-polarity protection. Selection advice: pick the voltage grade to match your peak reverse voltage with margin — 1N4002 (100 V), 1N4005 (600 V) or 1N4007 (1000 V) are the neighbors in the same DO-41 footprint. For switching supplies use an ultrafast type like UF5408 instead, since this is a standard-recovery part. Evidence: Vishay 1N4001–1N4007 datasheet confirms 1 A, 400 V, 30 A surge, DO-41 and 1.1 V forward voltage. Match the full 1N4004 code — the digit sets the voltage rating. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

1N4005 is a 1 A standard-recovery rectifier diode from the 1N400x family — 600 V repetitive peak reverse voltage, 1 A average forward current, 30 A surge capability, axial DO-41 (DO-204AL) package, 1.1 V maximum forward voltage, -65 to +150 °C. The 600 V rating is the selection point: the middle of the 1N4001–1N4007 voltage ladder, for mains-derived rectifiers, relay flyback clamps and reverse-polarity protection. Selection advice: pick the voltage grade to match your peak reverse voltage with margin — 1N4004 (400 V) or 1N4007 (1000 V) are the neighbors in the same DO-41 footprint. For switching supplies use an ultrafast type like UF5408 instead, since this is a standard-recovery part. Evidence: Vishay 1N4001–1N4007 datasheet confirms 1 A, 600 V, 30 A surge, DO-41 and 1.1 V forward voltage. Match the full 1N4005 code — the digit sets the voltage rating. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

1N4006 is a general-purpose 1 A rectifier diode in DO-41 — 800 V repetitive peak reverse voltage, 1 A average rectified current, 30 A non-repetitive surge, 1.1 V maximum forward voltage at 1 A, 5 µA reverse leakage, -65 to +150 °C, through-hole axial. The 800 V rating is the selection point: the mid-voltage member of the 1N400x family — choose this grade when your circuit never sees more than 800 V, and step up to the 1N4007 for higher-voltage margins. Selection advice: standard recovery (>500 ns) suits mains-frequency rectification only, not fast switching — use an ultrafast diode for switch-mode outputs. The silver band marks the cathode. Evidence: manufacturer datasheets and distributor listings confirm 800 V, 1 A, 30 A surge and DO-41. Match the full 1N4006 code for voltage grade. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

1N4007 is a 1 A, 1000 V general-purpose rectifier diode in a DO-41 axial package — the default choice for mains-frequency rectification, reverse-polarity protection and freewheeling in low-frequency circuits. Its advantage is the 1000 V rating at commodity pricing: one part number covers the full range of offline and low-voltage rectification tasks, simplifying spares. Selection advice: the 1N400x family spans 50 V (1N4001) to 1000 V (1N4007) in the same package — a lower-voltage sibling looks identical but will fail in a high-voltage circuit, so match the full 1N4007 code. For switching supplies above a few kHz, choose a fast-recovery type like the FR107 or UF4007 instead; standard-recovery diodes overheat at high frequency. As a jellybean part, require lot traceability against remarked stock.

1N4148 is the industry-standard high-speed switching diode — 100 V repetitive reverse voltage, 200 mA average forward current, 4 ns reverse recovery — in a DO-35 axial glass package. The 4 ns trr is the selection point: fast enough for megahertz switching, clamping and reverse-polarity steering in signal paths, where a 1N4007’s microsecond-scale recovery would distort or overheat. Selection advice: the bare 1N4148 code is the base part — onsemi ships it as 1N4148-T50A (ammo pack) or 1N4148-T50R (reel), so quote the suffixed code to get the right packing. For SMD boards the electrical equivalents are LL4148 (SOD-80) and 1N4148W (SOD-123), the same die in surface-mount packages. 1N914 is the older JEDEC number most vendors treat as interchangeable, but 1N4148’s leakage specification is tighter — stay with 1N4148 for precision clamping. Active through distribution. Parameters trace to the manufacturer datasheet; state quantity, packing and date-code requirements in your RFQ — we reconfirm the offered lot before quotation and reply within 24 hours.

1N4148W-13-F is a Diodes Incorporated 1N4148W fast switching diode in SOD-123, 10,000-piece 13-inch reel — 100 V repetitive peak reverse voltage, 300 mA continuous forward current, 4 ns maximum reverse recovery time, −55 °C to +150 °C. The -13-F code is the selection point: the 13-inch reel of 10,000 — the deep-volume code for a part that ships on nearly every switching, clamping and protection BOM in the industry. Selection advice: the 1N4148W is the default answer for signal switching, freewheeling on small relays, and ESD/logic clamping up to 100 V — but note the 300 mA continuous rating; for power rectification or higher surge, move to a Schottky or rectifier family instead. Against the WS SOD-323 codes: pick SOD-123 when the slightly larger package eases handling; pick SOD-323 when board density rules. Evidence: Diodes Inc and distributor data confirm 100 V, 300 mA, 4 ns trr, SOD-123 and 10,000-piece reel. Match the full 1N4148W-13-F code.

1N4148W-7-F is a fast small-signal switching diode from Diodes Incorporated in a SOD-123 surface-mount package, for clamping, protection and high-speed switching in general electronic circuits. Its advantage is the combination of nanosecond-scale switching speed and a tiny footprint, which is why the 1N4148 remains the default choice for signal-path switching across the industry. Selection advice: the W denotes the SOD-123 package and -7-F the tape-and-reel packing and lead-free finish — the classic 1N4148 also exists in DO-35 glass axial and other SMD packages, so the full code must match your assembly process. This is a high-volume commodity part where counterfeit and re-marked stock circulates: require lot traceability and buy the exact qualified code.
