MMSZ5232B

1N4733A is an onsemi 5.1 V Zener diode, 1 W maximum power dissipation, axial-lead DO-41 (DO-204AL) package — 5.1 V nominal Zener voltage at 49 mA test current, 7 Ω maximum Zener impedance, 10 µA maximum reverse leakage at 1 V, temperature coefficient −0.01 to +0.04 %/°C, color band marking the cathode. The 5.1 V value is the selection point: it is the natural shunt reference and overvoltage clamp for 5 V logic rails — a one-part overvoltage crowbar, reference or transient clamp where a precision IC reference would be overkill. Selection advice: the bare 1N4733A code is the general through-hole form; the -A suffix is ammo pack and -T is tape and reel — match the suffix to your insertion equipment. Note that only the -T50R variant is listed obsolete per PDN PD24582X; the exact code 1N4733A remains Active. onsemi lists 1N4733A as Active. Evidence: onsemi 1N4728A–1N4761A datasheet and distributor listings confirm 5.1 V, 1 W, 49 mA, DO-41 and Active status. Match the full 1N4733A code.

onsemi lists 1N4742A as Active — a Zener diode, VZ typ 12 V at IZT 21 mA, P max 1 W, axial-lead DO-41 package. The 12 V Zener voltage is the selection point: a simple, robust shunt reference and overvoltage clamp for 12 V rails, gate protection and signal limiting. Selection advice: the 1N47xx family spans 3.3 V to 100 V in the same DO-41 package — a wrong-voltage sibling looks identical, so match the full 1N4742A code. Verify your bias current keeps the diode in breakdown within its 1 W dissipation limit. Parameters verified against the onsemi official product page.

BZX84C5V1LT1G is an onsemi 5.1 V Zener diode in SOT-23, tape and reel — for voltage regulation and reference clamping: rail clamps, bias references and overvoltage shunts. 5.1 V nominal at 5 mA test current with 300 mW dissipation is the selection point: the industry-standard SOT-23 Zener footprint. Selection advice: the C denotes the tolerance band — C is ±6%, while the B-suffixed BZX84B5V1 is the tighter ±2% version; choose B where the reference accuracy matters, C where cost matters. The T1G suffix denotes tape and reel. −65 °C to +150 °C. onsemi lists this part as Active through distribution; no automotive qualification is claimed for this suffix. Parameters verified against onsemi documentation and distributor listings.

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.

MBR0520LT1G is an onsemi Schottky power rectifier — 500 mA, 20 V, forward drop maximum 0.385 V at 0.5 A, SOD-123 package, tape and reel, MSL 1. The 0.385 V forward drop is the selection point: one of the lowest-drop Schottkys in SOD-123 — for reverse-polarity protection and OR-ing on low-voltage rails where every millivolt of drop matters. Selection advice: onsemi lists the MBR0520LT1G as Active. The T1G suffix denotes tape and reel — match it to your assembly process. At 500 mA in SOD-123, verify the copper pour under the pads handles the dissipation at your worst-case ambient. Evidence: onsemi data confirms Active, 500 mA, 20 V, 0.385 V VF, SOD-123, tape and reel. Match the full MBR0520LT1G code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

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.

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.
