Product details
Overview
RGP10GEHE3/91 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); it serves as a freewheeling or output rectifier in AC/DC adapters and telecom DC-DC converters.
For engineers reviewing the RGP10GEHE3/91 datasheet, RGP10GEHE3/91 pinout, RGP10GEHE3/91 application, or RGP10GEHE3/91 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 implements a single silicon PN junction with cavity-free glass passivation to ensure stable leakage performance and high reliability under thermal cycling. Its Superectifier® structure enables fast recovery (trr = 150 ns) while maintaining low forward voltage drop (VF = 1.3 V) and high surge capability (IFSM = 30 A).
Designed for operation up to TJ = 175 °C, RGP10GEHE3/91 supports high-temperature environments typical in enclosed power supplies. The DO-41 package provides standardized lead spacing (0.375" / 9.5 mm) and meets UL 94 V-0 flammability requirements with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse blocking voltage, suitable for 280 V RMS input rectification in universal-input SMPS |
| IF(AV) | 1.0 A - average forward current at TA = 55 °C with 0.375" lead length, defines continuous power handling in linear and switch-mode topologies |
| trr | 150 ns - measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables efficient high-frequency rectification up to ~200 kHz |
| VF | 1.3 V @ 1.0 A - forward voltage drop directly impacts conduction loss and thermal design in output stage rectifiers |
| IR | 5.0 μA @ 25 °C - low leakage ensures minimal standby power loss in offline power supplies |
| TJ max. | 175 °C - maximum junction temperature allows operation in thermally constrained enclosures without derating penalties |
Pinout & Package
Package: DO-41 (DO-204AL), axial-leaded, epoxy-molded with glass body; polarity indicated by cathode band; RoHS-compliant E3 suffix with matte tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of load or transformer secondary; must withstand IFSM = 30 A surge |
| Cathode | Forward current exit point | Marked with color band; ties to positive rail or switching node; handles full reverse voltage during off-state |
Key Features
| Feature | Design Value |
|---|---|
| Superectifier® structure | Enhanced junction reliability under repeated thermal stress, validated for >1000 cycles between -65 °C and +175 °C |
| Cavity-free glass passivation | Eliminates moisture ingress paths, reducing long-term IR drift and preventing premature failure in humid environments |
| Fast switching (trr = 150 ns) | Minimizes reverse recovery loss in flyback and forward converters operating above 100 kHz |
| High surge rating (IFSM = 30 A) | Withstands inrush currents during cold-start of AC/DC supplies without degradation |
Applications
| AC/DC Adapter Output Rectification | Telecom DC-DC Converter Freewheeling Diode |
|---|---|
Use Scenario: Secondary-side rectification in 12–24 V, 10–25 W wall adapters with universal AC input (90–264 VAC). IC Role / Device Role / Timing Role: Power rectifier converting high-frequency transformer output to regulated DC; operates in discontinuous conduction mode. Use Value: Low VF (1.3 V) reduces conduction loss; 400 V VRRM accommodates reflected voltage spikes in flyback topology. | Use Scenario: Freewheeling path in isolated 48 V input telecom DC-DC modules delivering 3.3–12 V at ≤1 A. IC Role / Device Role / Timing Role: Clamp diode across primary-side MOSFET or secondary synchronous rectifier gate drive transformer. Use Value: 150 ns trr prevents cross-conduction losses during high-frequency (200–500 kHz) switching transitions. |
| Inverter Auxiliary Power Supply | Industrial Control Board Input Protection |
Use Scenario: Standby power generation from main DC bus in motor drive inverters using auxiliary flyback converter. IC Role / Device Role / Timing Role: Primary-side rectifier feeding 15 V bias rail for gate drivers and MCU; subjected to bus transients up to 600 V. Use Value: 400 V VRRM plus 30 A IFSM ensures robustness against line surges and inductive kickback events. | Use Scenario: Reverse-polarity and back-EMF protection on 24 V DC input terminals of PLC I/O modules. IC Role / Device Role / Timing Role: Series-connected input protection diode limiting fault current during accidental reverse connection or inductive load dump. Use Value: 175 °C TJ max. and low IR (5.0 μA) maintain integrity over extended industrial temperature range (-40 to +85 °C ambient). |
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 (faster), VF = 1.3 V, DO-41 package | Better suited for >300 kHz operation due to shorter trr; higher cost and tighter VF distribution | Select when minimizing reverse recovery loss is critical and layout allows same footprint |
| 1N4937G | VRRM = 600 V, trr = 200 ns, VF = 1.2 V, DO-41 package | Higher voltage rating trades off slightly slower recovery; preferred where input transients exceed 400 V | Choose for enhanced margin in unregulated or wide-range industrial inputs |
Compared with STTH1R04 and 1N4937G, RGP10GEHE3/91 offers balanced speed (150 ns), low VF, and proven reliability in cost-sensitive consumer power supplies-making it optimal for legacy designs requiring DO-41 compatibility and no PCB changes.

FAQ
What is the maximum junction temperature rating for RGP10GEHE3/91?
RGP10GEHE3/91 has a maximum junction temperature (TJ max.) of +175 °C, enabling reliable operation in thermally demanding environments such as enclosed power supplies and industrial control units. This rating is specified in the Vishay datasheet Document Number 88700 and verified under steady-state and transient thermal conditions per JEDEC standards.
Is RGP10GEHE3/91 RoHS-compliant and lead-free?
Yes, RGP10GEHE3/91 is RoHS-compliant and lead-free, indicated by the "E3" suffix. It meets JESD 201 Class 1A whisker test requirements and features matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. The molding compound complies with UL 94 V-0 flammability rating.
What does the "G" in RGP10GEHE3/91 signify?
The "G" in RGP10GEHE3/91 denotes the 400 V VRRM variant within the RGP10x family. Per Vishay's ordering nomenclature, RGP10A = 50 V, RGP10B = 100 V, RGP10D = 200 V, RGP10G = 400 V, RGP10J = 600 V, etc. The "EHE3/91" suffix indicates tape-and-reel packaging (E3) and specific reel configuration (91).
Can RGP10GEHE3/91 replace RGP10JEHE3/91 in a design?
No-RGP10GEHE3/91 (400 V VRRM) is not a direct replacement for RGP10JEHE3/91 (600 V VRRM). Substituting it risks reverse breakdown under transient overvoltage conditions. Always verify peak reverse stress in the target circuit; use RGP10JEHE3/91 only where ≥600 V blocking is required.
What is the reverse recovery time (trr) specification for RGP10GEHE3/91?
RGP10GEHE3/91 has a maximum reverse recovery time (trr) of 150 ns, tested at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the Vishay datasheet. This value is confirmed for the "G" variant and distinguishes it from slower variants like RGP10J (250 ns) and RGP10M (500 ns).
