Product details
Overview
1N4934GP-M3/73 from Vishay General Semiconductor is a glass passivated junction fast switching plastic rectifier diode rated for 100 V repetitive peak reverse voltage, 1.0 A average forward current, 30 A surge capability, 200 ns reverse recovery time, and 1.2 V forward voltage at 1.0 A - used in high-efficiency AC/DC power supply rectification and freewheeling paths.
For engineers reviewing the 1N4934GP-M3/73 datasheet, 1N4934GP-M3/73 pinout, 1N4934GP-M3/73 application, or 1N4934GP-M3/73 equivalent, this page delivers verified electrical parameters, DO-41 package details, thermal behavior, and validated alternative diodes for legacy power conversion designs.
Technical Context
This device implements a Superectifier® structure with cavity-free glass passivation to enhance reliability under thermal cycling and humidity stress. Its fast 200 ns reverse recovery time and low 5.0 μA leakage at 25 °C support efficient high-frequency rectification in offline SMPS and DC-DC converters.
Designed for single-diode operation in DO-41 (DO-204AL) through-hole package, it features matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 1A whisker resistance. Maximum junction temperature is rated at +175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse blocking voltage; defines safe AC input voltage derating in bridge or half-wave rectifiers |
| IF(AV) | 1.0 A at 75 °C with 0.375" lead length - continuous DC output current capability in linearly derated thermal envelope |
| IFSM | 30 A - non-repetitive surge rating for handling inrush currents during power-up or line transients |
| trr | 200 ns - reverse recovery time at IF = 1.0 A, VR = 30 V; enables operation up to ~500 kHz switching frequencies |
| VF | 1.2 V at IF = 1.0 A - forward conduction loss directly impacts conduction efficiency and thermal rise in rectifier stage |
| TJ(max) | +175 °C - maximum junction temperature; supports high ambient operation in enclosed power supplies |
| CJ | 15 pF at 4.0 V, 1 MHz - junction capacitance affects high-frequency noise coupling and snubber design |
Pinout & Package
Package: DO-41 (DO-204AL), axial-leaded, molded epoxy over glass body with UL 94 V-0 flammability rating. Cathode indicated by color band on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Forward current entry | Connected to AC source or switch node in freewheeling path; must handle full IF(AV) and IFSM |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Connected to output rail or ground return; withstands full VRRM when reverse biased |
Key Features
| Feature | Design Value |
|---|---|
| Superectifier® structure | Enhanced reliability via cavity-free glass passivation - reduces risk of junction corrosion and parametric drift in humid environments |
| Fast switching (200 ns trr) | Enables higher-frequency operation than standard rectifiers, reducing transformer size and improving power density |
| Low leakage (5.0 μA at 25 °C) | Minimizes standby power loss in no-load or light-load conditions of AC/DC adapters |
| High surge rating (30 A IFSM) | Withstands repeated cold-start surges without degradation - critical for universal-input offline supplies |
| Solderable matte tin leads | Complies with J-STD-002 and JESD 22-B102; supports wave and hand-soldering without lead oxidation issues |
Applications
| AC/DC Power Supply Rectification | Inverter Freewheeling Diode |
|---|---|
Use Scenario: Full-wave bridge rectification in 85–265 VAC input offline SMPS for consumer electronics. IC Role / Device Role / Timing Role: Discrete rectifier diode conducting during positive/negative half-cycles to generate unregulated DC bus. Use Value: 100 V VRRM provides margin above 1.414 × 265 VAC peak; 200 ns trr limits switching losses at 65–100 kHz operation. | Use Scenario: Freewheeling path across inductive loads in motor drive inverters and UPS systems. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path when IGBT/MOSFET switches turn off. Use Value: 30 A IFSM handles transient inductive kickback; 1.2 V VF minimizes conduction loss during flyback interval. |
| DC-DC Converter Output Stage | Telecom Power Rectification |
Use Scenario: Secondary-side synchronous rectification replacement in isolated flyback or forward converters. IC Role / Device Role / Timing Role: Standard rectifier in low-cost, non-synchronous output stage delivering regulated 3.3–24 V DC. Use Value: 1.0 A IF(AV) supports up to ~12 W output; DO-41 package allows manual rework and high-voltage creepage spacing. | Use Scenario: Input rectification in telecom -48 V DC backup power systems and AC-powered network equipment. IC Role / Device Role / Timing Role: Primary rectifier converting AC mains to bulk DC before PFC and isolation stages. Use Value: 175 °C TJ(max) ensures robustness under sustained high ambient temperatures in telecom cabinets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4934G | Same VRRM, IF(AV), trr, and DO-41 package; differs only in packaging suffix (bulk vs. ammo pack) and RoHS status (non-RoHS base version) | No functional difference; suitable where RoHS compliance is not required and cost sensitivity favors legacy stock | Select 1N4934G only if RoHS exemption applies and traceability requirements permit non-E3 material |
| STTH1R06 | 100 V VRRM, 1.0 A IF(AV), but faster 75 ns trr and lower 0.95 V VF; TO-220AC package, not DO-41 | Requires PCB layout change; better suited for higher-efficiency or thermally constrained designs where surface-mount or heatsinking is preferred | Choose STTH1R06 only when upgrading efficiency or thermal performance justifies mechanical redesign |
Compared with 1N4934GP-M3/73, 1N4934G offers identical electrical behavior without RoHS compliance, while STTH1R06 delivers superior speed and lower forward drop but demands TO-220 footprint and thermal management - neither is pin-compatible.

FAQ
Is 1N4934GP-M3/73 RoHS-compliant?
Yes, 1N4934GP-M3/73 is RoHS-compliant. The "E3" suffix in the full ordering code (e.g., 1N4934GP-E3/73) confirms compliance with EU RoHS Directive 2011/65/EU and meets JESD 201 Class 1A whisker resistance. This applies to the M3/73 variant supplied by Vishay in ammo pack format.
What does the "M3/73" suffix mean in 1N4934GP-M3/73?
The "M3/73" suffix identifies the packaging configuration: "M3" denotes Vishay's internal tape-and-reel or bulk packaging standard, and "73" specifies ammo pack packaging with 3,000 units per pack. It replaces older "E3/73" notation but retains identical electrical specs, RoHS compliance, and DO-41 mechanical form factor as 1N4934GP-E3/73.
Can 1N4934GP-M3/73 replace 1N4007 in a power supply design?
No - 1N4934GP-M3/73 is not a direct replacement for 1N4007. While both are DO-41 rectifiers, 1N4934GP-M3/73 has 100 V VRRM versus 1N4007's 1000 V, and its 200 ns trr is optimized for switching use, whereas 1N4007 is a general-purpose 30 μs slow rectifier. Substitution requires verification of voltage margin and EMI implications.
What is the maximum operating temperature for 1N4934GP-M3/73?
The maximum junction temperature for 1N4934GP-M3/73 is +175 °C, and the storage temperature range is –65 °C to +175 °C. At ambient temperatures above 75 °C, derating applies: average forward current decreases linearly to zero at +175 °C per the published derating curve in Vishay document 88509.
Why is 1N4934GP-M3/73 marked "Not for New Designs"?
Vishay designates 1N4934GP-M3/73 as "Not for New Designs" because newer platforms favor surface-mount fast rectifiers (e.g., SMA/SMB packages) or integrated solutions. However, the part remains fully manufactured and supported for repair, maintenance, and legacy production - no obsolescence notice has been issued.
