Product details
Overview
RGP10B-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, and 30 A non-repetitive surge current; it features 150 ns reverse recovery time, 1.3 V forward voltage at 1.0 A, and operates up to 175 °C junction temperature - used in AC-DC adapters and DC-DC converter freewheeling paths.
For engineers reviewing the RGP10B-M3/73 datasheet, RGP10B-M3/73 pinout, RGP10B-M3/73 application, or RGP10B-M3/73 equivalent, key selection criteria include its DO-41 package compatibility, low leakage (5.0 μA at 25 °C), fast trr performance, thermal robustness (TJ max = 175 °C), and suitability for high-efficiency switching power supplies requiring reliable unidirectional conduction.
Technical Context
This device implements a single-diode Superectifier® structure with cavity-free glass passivation, enabling stable operation under thermal cycling and high-humidity conditions. Its fast recovery (trr = 150 ns) and low forward voltage (VF = 1.3 V) reduce switching losses and conduction losses simultaneously in high-frequency rectification circuits.
The RGP10B-M3/73 is optimized for discrete rectification in off-line and isolated DC-DC topologies where low IR (5.0 μA at 25 °C) minimizes standby power loss and high IFSM (30 A) supports transient overload tolerance without failure.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse blocking capability, suitable for 70 V RMS input stages |
| IF(AV) | 1.0 A - continuous forward current rating at 55 °C ambient with 9.5 mm lead length |
| IFSM | 30 A - peak surge current handling for 8.3 ms half-sine, supporting inrush and fault transients |
| trr | 150 ns - fast reverse recovery enables operation up to ~500 kHz switching frequencies |
| VF | 1.3 V @ 1.0 A - low conduction loss improves efficiency in low-voltage output rectifiers |
| IR | 5.0 μA @ 25 °C - minimal leakage preserves efficiency in standby and light-load conditions |
| TJ max | 175 °C - extended thermal range allows use in compact, thermally constrained enclosures |

Applications
| AC-DC Adapter Rectification | DC-DC Converter Freewheeling |
|---|---|
Use Scenario: Rectifying 50/60 Hz or high-frequency AC input in wall adapters and open-frame power supplies. IC Role / Device Role / Timing Role: Primary-side unidirectional conduction element converting AC to pulsating DC. Use Value: Low VF (1.3 V) reduces heat generation; 100 V VRRM safely handles 70 V RMS inputs with margin. | Use Scenario: Providing current recirculation path across inductive loads in buck, flyback, and forward converters. IC Role / Device Role / Timing Role: Freewheeling diode clamping inductive kickback during switch-off phase. Use Value: 150 ns trr ensures clean turn-off before next switching cycle, minimizing cross-conduction loss. |
| Inverter Output Stage | Telecom Power Module |
Use Scenario: Output rectification in low-power inverters converting DC to modified sine-wave AC. IC Role / Device Role / Timing Role: Synchronous or asynchronous rectifier in low-voltage output stage. Use Value: 30 A IFSM withstands motor startup surges; 175 °C TJ max supports sealed enclosure operation. | Use Scenario: Secondary-side rectification in telecom brick modules requiring high reliability and low leakage. IC Role / Device Role / Timing Role: Isolated DC output rectifier delivering stable +5 V, +12 V, or +48 V rails. Use Value: 5.0 μA IR at 25 °C maintains tight regulation during no-load standby; DO-41 fits legacy board layouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast-switching rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4934GP-E3/54 | VRRM = 100 V, trr = 200 ns, VF = 1.3 V, same DO-41 package | Slower recovery increases switching loss above 250 kHz; otherwise functionally interchangeable | Acceptable where trr margin is relaxed and cost sensitivity favors Vishay's alternate series |
| US1B-E3/54 | VRRM = 100 V, trr = 75 ns, VF = 1.7 V, same DO-41 package | Higher VF increases conduction loss; faster trr benefits >1 MHz designs but raises EMI risk | Preferred when ultra-fast recovery is critical and higher forward drop is tolerable |
Compared with RGP10B-M3/73, 1N4934GP-E3/54 trades speed for identical VF and cost, while US1B-E3/54 prioritizes trr at the expense of VF and thermal dissipation - selection depends on whether conduction loss, switching loss, or layout compatibility dominates the design constraint.

FAQ
What is the maximum junction temperature rating for RGP10B-M3/73?
The RGP10B-M3/73 has a maximum junction temperature (TJ max) of +175 °C, verified per Vishay's datasheet revision 26-Jan-2022. This rating allows operation in thermally constrained environments such as enclosed power supplies or high-ambient industrial settings. Derating curves confirm 1.0 A IF(AV) is maintained up to 55 °C ambient with 9.5 mm lead length. Exceeding TJ max risks permanent degradation of the glass-passivated junction in RGP10B-M3/73.
Is RGP10B-M3/73 suitable for new designs?
No - Vishay explicitly marks RGP10B-M3/73 as "Not for New Designs" in its official documentation (Document Number: 88700, Revision: 26-Jan-2022). While fully functional and supported for existing production, designers are advised to evaluate newer alternatives like the VS-1N4934GP-E3/54 or US1B-E3/54 for new projects. RGP10B-M3/73 remains available through Aetrix Electronics for legacy BOM continuity and repair programs.
What does the "M3/73" suffix indicate in RGP10B-M3/73?
The "M3/73" suffix denotes Vishay's packaging configuration: "M3" specifies the taping and reel option per internal manufacturing code, and "73" indicates ammo pack packaging containing 3000 units. This differs from "/54", which refers to 13-inch paper tape and reel (5500 units). Both share identical electrical and thermal specifications; only mechanical packaging differs. The RGP10B-M3/73 part number uniquely identifies this ammo-pack variant of the RGP10B rectifier.
How does the reverse recovery time of RGP10B-M3/73 compare to other RGP10x variants?
RGP10B-M3/73 has a specified trr of 150 ns, matching RGP10A and differing from RGP10D (250 ns) and RGP10G+ (500 ns). All variants share identical IF(AV), IFSM, VF, and IR ratings - only VRRM and trr scale across the family. Thus, RGP10B-M3/73 delivers the fastest recovery in the 100 V class of the RGP10x series, making it optimal for higher-frequency switching applications where RGP10D or RGP10G would incur excess switching loss.
Does RGP10B-M3/73 meet RoHS and lead-free requirements?
Yes - RGP10B-M3/73 carries the "E3" base suffix (implied in M3/73 per Vishay's ordering conventions), confirming RoHS compliance and lead-free matte tin plating per J-STD-002 and JESD 22-B102. It also passes JESD 201 Class 1A whisker testing. The molding compound meets UL 94 V-0 flammability rating, and full material compliance details are documented in Vishay's "Material Categorization" reference (www.vishay.com/doc?99912).
