Product details
Overview
RGP10GHM3/73 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 RGP10GHM3/73 datasheet, RGP10GHM3/73 pinout, RGP10GHM3/73 application, or RGP10GHM3/73 equivalent, key selection criteria include VRRM=400 V, trr=150 ns, VF=1.3 V at 1.0 A, IR=5.0 μA at 25 °C, and DO-41 mechanical compatibility with legacy through-hole power supply designs.
Technical Context
This device employs a Superectifier® structure with cavity-free glass-passivated junction to ensure high reliability under thermal cycling and humidity stress. Its fast switching performance (trr = 150 ns) and low forward voltage (VF = 1.3 V) support high-efficiency operation in 50–100 kHz SMPS topologies.
The RGP10GHM3/73 operates across –65 °C to +175 °C junction temperature range and sustains 30 A non-repetitive surge current (IFSM), making it suitable for transient-heavy industrial power rails where robustness exceeds standard general-purpose rectifiers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse blocking capability, defines usable input voltage range in bridge or single-diode rectification |
| IF(AV) | 1.0 A at 55 °C ambient with 0.375" lead length - continuous DC output current rating under standard PCB mounting |
| trr | 150 ns - enables efficient operation up to ~100 kHz switching frequencies with minimal switching loss |
| VF | 1.3 V at 1.0 A - contributes to <1.3 W conduction loss at full load, critical for thermal management in compact adapters |
| IR | 5.0 μA at 25 °C - ensures low standby leakage in offline power supplies meeting energy efficiency standards |
| TJ max. | +175 °C - supports operation in high-ambient environments such as enclosed industrial enclosures or automotive under-hood proximity |
| RθJA | 55 °C/W - thermal resistance from junction to ambient, used to calculate temperature rise under real-world PCB layout conditions |
Pinout & Package
Package: DO-41 (DO-204AL), axial-leaded, epoxy-molded with glass-passivated die; cathode indicated by color band on body.

| Glass-passivated junction | Enables stable electrical parameters over 10+ years of operation without passivation layer delamination |
| Fast switching (trr = 150 ns) | Reduces reverse recovery charge (Qrr), lowering EMI and losses in flyback and forward converter freewheeling paths |
| Solder dip tolerance (275 °C, 10 s) | Supports wave soldering process without junction degradation or bond lift, ensuring manufacturing yield |
| UL 94 V-0 molding compound | Meets flame-retardancy requirements for Class II consumer power supplies and telecom equipment |
Applications
| AC/DC Adapter Output Rectification | DC/DC Converter Freewheeling Diode |
|---|---|
Use Scenario: Secondary-side rectification in 5–24 V, 10–30 W wall adapters with universal AC input. IC Role / Device Role / Timing Role: Unidirectional current path converting transformer AC output to regulated DC; no timing function. Use Value: 150 ns trr minimizes switching loss at 65 kHz operation, while 1.3 V VF maintains >85% efficiency at full load. | Use Scenario: Freewheeling path in 12 V input, 5 V output buck converter for industrial control modules. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path during MOSFET off-time; critical for energy transfer efficiency. Use Value: 30 A IFSM withstands inductor current spikes during startup or overload, preventing catastrophic failure. |
| Inverter Auxiliary Power Supply | Telecom Line Card Protection |
Use Scenario: Input rectification stage of isolated auxiliary 15 V supply powering gate drivers in 3-phase inverters. IC Role / Device Role / Timing Role: Converts rectified AC to DC bus for biasing control circuitry; operates continuously under high ambient temperature.

IC Role / Device Role / Timing Role: Blocks reverse current and clamps transients via controlled avalanche behavior during lightning-induced surges. Use Value: 400 V VRRM provides 2× margin over nominal 48 V system, while 5.0 μA IR preserves battery backup runtime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R04 | VRRM = 400 V, trr = 35 ns, VF = 1.3 V, DO-41 package | Lower trr improves high-frequency efficiency but increases cost and may require EMI filtering revalidation | Select when operating above 150 kHz or requiring lowest possible Qrr in space-constrained designs |
| 1N4937G | VRRM = 600 V, trr = 200 ns, VF = 1.2 V, DO-41 package | Higher VRRM suits 230 VAC-fed supplies with poor input regulation; slightly slower recovery | Select when system-level overvoltage margin >600 V is required and 50 ns trr penalty is acceptable |
Compared with STTH1R04 and 1N4937G, the RGP10GHM3/73 offers balanced performance: identical VRRM and VF to STTH1R04 but higher trr, and identical package/mechanical fit to 1N4937G while delivering lower IR and tighter trr consistency across temperature.

FAQ
What is the maximum junction temperature rating for RGP10GHM3/73?
The RGP10GHM3/73 has a maximum junction temperature (TJ max.) of +175 °C, verified per Vishay specification document 88700. This rating allows operation in high-ambient environments such as enclosed industrial power supplies or near heat-generating components. Derating curves in the datasheet define safe IF(AV) limits above 55 °C ambient, and thermal design must account for RθJA = 55 °C/W under standard mounting conditions. The RGP10GHM3/73 maintains parameter stability up to this limit without permanent degradation.
Is RGP10GHM3/73 suitable for new designs?
No - Vishay explicitly marks the RGP10 series as "Not for New Designs" in revision 26-Jan-2022 documentation. While RGP10GHM3/73 remains available for legacy production and repair, Vishay recommends evaluating newer alternatives like the VS-1N4937G or STTH1R04 for new projects. The RGP10GHM3/73 continues to be supported with full parametric data and packaging integrity, but long-term obsolescence planning is advised. Aetrix Electronics provides continuity support for existing RGP10GHM3/73 BOMs.
What does the "HM3/73" suffix mean in RGP10GHM3/73?
The "HM3/73" suffix in RGP10GHM3/73 indicates Vishay's internal packaging and reel configuration: "HM3" denotes the E3-compliant matte tin-plated leads and RoHS-compliant construction, while "73" specifies ammo pack packaging with 3000 units per pack. This matches ordering information in document 88700, where RGP10J-E3/73 is shown as the equivalent base part with same electrical specs. The RGP10GHM3/73 is electrically identical to RGP10G-E3/73 - the "H" confirms VRRM = 400 V, and "M3" reflects updated manufacturing traceability.
How does the glass-passivated junction improve reliability of RGP10GHM3/73?
The glass-passivated junction in RGP10GHM3/73 eliminates micro-cavities that trap moisture and cause corrosion under thermal cycling or high humidity. Unlike silicon dioxide passivation, glass forms a hermetic seal directly over the PN junction, maintaining stable IR and VF over 10+ years of field operation. This structure is validated per JESD22-A101 humidity testing and supports use in outdoor telecom enclosures or industrial washdown environments. The RGP10GHM3/73 leverages this for consistent performance where standard epoxy-passivated diodes may drift.
What is the reverse recovery time (trr) of RGP10GHM3/73, and how is it measured?
The RGP10GHM3/73 has a maximum reverse recovery time (trr) of 150 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per JEDEC test conditions. This value is confirmed in the Electrical Characteristics table of Vishay document 88700. The trr directly impacts switching loss and EMI generation in high-frequency converters; a 150 ns trr enables efficient operation up to ~100 kHz. Designers should verify actual trr in circuit using oscilloscope-based double-pulse testing, as layout parasitics can affect measured values. The RGP10GHM3/73 delivers consistent trr across its rated temperature range.
