Product details
Overview
RGP10G-M3/73 from Vishay General Semiconductor is a glass-passivated junction fast switching plastic rectifier diode in DO-41 package, rated for 400 V repetitive peak reverse voltage (VRRM), 1.0 A average forward current (IF(AV)), and 150 ns reverse recovery time (trr), used as freewheeling or output rectifier in AC/DC adapters and DC/DC converters.
For engineers reviewing the RGP10G-M3/73 datasheet, RGP10G-M3/73 pinout, RGP10G-M3/73 application, or RGP10G-M3/73 equivalent, key selection criteria include its 150 ns trr for high-frequency switching efficiency, 1.3 V forward voltage at 1.0 A, 5.0 μA reverse leakage at 25 °C, DO-41 mechanical compatibility, and suitability for commercial-grade power supply designs requiring reliability under surge and thermal stress.
Technical Context
This device implements a Superectifier® structure with cavity-free glass-passivated junction to enhance reliability and reduce failure modes under thermal cycling and humidity exposure. Its fast switching behavior stems from optimized carrier lifetime control, enabling efficient operation in 20–100 kHz SMPS topologies.
The RGP10G-M3/73 operates across –65 °C to +175 °C junction temperature range and supports solder dip up to 275 °C for 10 s per JESD 22-B106. It exhibits 15 pF junction capacitance at 4.0 V / 1 MHz and 55 °C/W junction-to-ambient thermal resistance with 0.375" lead length on PCB.

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4937G | VRRM = 600 V, trr = 200 ns, VF = 1.2 V @ 1.0 A | Higher voltage rating but slower recovery; better for 380 VAC front-end, less optimal for 100 kHz+ outputs | Select when higher reverse margin is needed and trr < 200 ns is acceptable |
| FR107 | VRRM = 1000 V, trr = 500 ns, VF = 1.3 V @ 1.0 A | Wider voltage range but significantly slower; suited for low-frequency linear supplies, not SMPS | Choose only for legacy 50/60 Hz rectification where speed is non-critical |
Compared with RGP10G-M3/73, the 1N4937G offers higher voltage headroom at moderate speed trade-off, while FR107 sacrifices speed for extreme voltage capability-making RGP10G-M3/73 the optimal balance for 400 V-class, medium-frequency SMPS rectification.

FAQ
What is the maximum junction temperature rating for RGP10G-M3/73?
The RGP10G-M3/73 has a maximum junction temperature (TJ max.) of +175 °C, allowing reliable operation in thermally constrained environments such as enclosed power adapters or densely packed industrial control boards. This rating is validated per Vishay's thermal characterization and supports derated current handling up to 125 °C ambient with appropriate PCB copper area.
Is RGP10G-M3/73 suitable for new designs?
No-RGP10G-M3/73 is marked "Not for New Designs" per Vishay document 88700 (Revision: 26-Jan-2022). While fully functional and supported for existing production, designers should evaluate Vishay's newer alternatives like the VS-1N4937GHM3 or automotive-qualified equivalents for long-term program viability.
What does the "M3/73" suffix indicate in RGP10G-M3/73?
The "M3" denotes Vishay's standard tape-and-reel packaging per EIA-481, and "73" specifies ammo pack delivery mode with 3000 units per pack. This differs from "/54", which indicates 13" diameter paper tape and reel (5500 units). Both share identical electrical and thermal specs for RGP10G-M3/73.
How does the 150 ns reverse recovery time of RGP10G-M3/73 impact converter efficiency?
The 150 ns trr of RGP10G-M3/73 directly reduces reverse recovery charge (Qrr), lowering switching losses in the 50–100 kHz range typical of flyback and forward converters. Compared to 500 ns devices like FR107, this yields measurable improvement in full-load efficiency-especially when paired with low-Qg MOSFETs-and reduces EMI from diode turn-off spikes.
Does RGP10G-M3/73 meet RoHS and lead-free soldering requirements?
Yes-RGP10G-M3/73 carries the "E3" base part number suffix (implied in M3/73 packaging code), confirming RoHS compliance and matte tin-plated leads qualified for lead-free reflow and solder dip up to 275 °C for 10 s per JESD 22-B106. Whisker resistance meets JESD 201 Class 1A.
