1N5819 is a Vishay 40 V / 1 A Schottky barrier rectifier in DO-41 — for low-voltage rectification and polarity protection: DC-DC outputs, freewheeling and reverse-battery guards. 0.6 V maximum forward voltage at 1 A is the selection point: roughly half the drop of a 1N4007, which directly cuts heat in 5–12 V supplies. Selection advice: the bare 1N5819 code is the base part — distributors list it as 1N5819-E3/54, where E3 denotes lead-free and 54 the packaging; quote the full code to get the right packing. The onsemi 1N5819RLG is the same 40 V / 1 A DO-41 footprint from a second manufacturer for supply resilience. 25 A surge, −65 °C to +150 °C. Vishay lists this part as Active through distribution. Parameters verified against Vishay documentation and distributor listings.

NRVB130T1G is an onsemi 30V 1A Schottky barrier rectifier in SOD-123 - for low-voltage rectification and protection: 0.35V typical forward voltage at 0.1A, 0.45V maximum at 0.7A, 60uA maximum reverse leakage at 30V, 5.5A non-repetitive surge current, guard ring for stress protection, -65C to 125C junction range. The low forward drop is the selection point: less power wasted as heat than a standard PN rectifier, which raises efficiency in DC-DC outputs and lets small SOD-123 boards run cooler at the same load. Business impact: one AEC-Q101 qualified, PPAP-capable diode covers freewheeling, reverse-polarity and low-voltage rectification across industrial and automotive programs, so a single qualified code serves multiple platforms. Selection advice: the NRVB prefix is the automotive-grade ordering code - the MBR130 is the commercial sibling; the T1G suffix is the 3000-piece tape-and-reel packing, and the cathode band marks polarity, so verify footprint orientation before reflow. Ranked #3 on the hqbuy.com real-time hot list (2026-10-16). Parameters verified against onsemi documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

SS34-E3/57T is a Vishay 40 V / 3 A Schottky barrier rectifier in SMC (DO-214AB), tape and reel — for low-voltage power conversion: DC-DC output rectification, freewheeling and reverse-polarity protection. 0.5 V forward voltage at 3 A is the selection point: Schottky drop cuts conduction loss roughly in half versus a standard PN rectifier at the same current. Selection advice: the E3/57T suffix denotes tape and reel packaging — quote the full suffix to get reel rather than bulk; the onsemi SS34 on this site is the same 40 V / 3 A SMC footprint from a second manufacturer, giving a cross-source option for supply resilience. 100 A surge capability, −55 °C to +125 °C. Vishay lists this part as Active through distribution. Parameters verified against Vishay documentation and distributor listings. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

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.

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.

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.

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.

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.
