Product details
Overview
GP08GHE3/73 from Vishay General Semiconductor is a glass passivated junction rectifier in DO-41 package, rated for 400 V repetitive peak reverse voltage (VRRM), 0.8 A average forward current (IF(AV)), and 25 A non-repetitive surge current (IFSM). It delivers low forward voltage drop (1.3 V at 0.8 A) and ultra-low leakage (5.0 μA at 25 °C), suited for AC/DC power supply input rectification in industrial power adapters.
For engineers reviewing the GP08GHE3/73 datasheet, GP08GHE3/73 pinout, GP08GHE3/73 application, or GP08GHE3/73 equivalent, key selection criteria include VRRM margin for line-voltage transients, thermal resistance (55 °C/W) under PCB-mounted conditions, trr of 2.0 μs for moderate-switching converters, and DO-41 lead-form compatibility with legacy through-hole layouts.
Technical Context
This Superectifier® diode uses cavity-free glass-passivated junction technology to ensure high reliability under thermal cycling and humidity stress. Its 175 °C maximum junction temperature and JESD22-B106-compliant solderability (275 °C, 10 s) support operation in enclosed, convection-cooled power supplies.
The device exhibits fast recovery (trr = 2.0 μs) and low junction capacitance (CJ = 8.0 pF at 4.0 V, 1 MHz), enabling use in freewheeling and snubber circuits where reverse recovery loss and capacitive loading must be minimized - without requiring soft-recovery optimization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - supports 230 VAC mains input with ≥2× safety margin against line surges |
| IF(AV) | 0.8 A - continuous DC output capability after rectification with 0.375" lead length at 55 °C ambient |
| IFSM | 25 A - withstands inrush currents during cold-start of switch-mode power supplies |
| VF | 1.3 V at 0.8 A - limits conduction loss to ≤1.04 W per diode in full-wave bridge configurations |
| IR | 5.0 μA at 25 °C - ensures minimal standby power loss in offline auxiliary supplies |
| trr | 2.0 μs - enables efficient operation up to ~100 kHz switching frequencies without excessive reverse recovery loss |
| RθJA | 55 °C/W - requires minimum 5 mm × 7 mm copper pad for thermal management at full load |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar general-purpose rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4007G-E3/54 | VRRM = 1000 V; VF = 1.1 V at 1.0 A; trr ≈ 30 μs; same DO-41 package | Higher voltage margin but slower recovery; unsuitable for >20 kHz freewheeling | Select when primary need is robust overvoltage protection, not speed |
| GP08DHE3/73 | VRRM = 200 V; identical VF, trr, package, and thermal specs | Limited to 115 VAC input designs; lower cost where 400 V margin is unnecessary | Choose for cost-sensitive 100–120 VAC applications with no surge risk |
Compared with GP08GHE3/73, the 1N4007G-E3/54 offers higher VRRM but significantly slower recovery, increasing switching loss in high-frequency converters; GP08DHE3/73 matches all dynamic specs but halves reverse voltage capability - making it viable only where system-level surge protection is externally implemented.

FAQ
What is the maximum junction temperature rating for GP08GHE3/73?
The GP08GHE3/73 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 sealed power supplies or high-ambient industrial enclosures. Derating curves in Figure 1 confirm usable current down to 0 A at 175 °C ambient when mounted with standard 0.375" lead length. The GP08GHE3/73 maintains specified VF and IR performance within this full range.
Is GP08GHE3/73 RoHS-compliant and lead-free?
Yes, GP08GHE3/73 is RoHS-compliant and lead-free. The "E3" suffix explicitly denotes Vishay's commercial-grade, RoHS-compliant construction with matte tin-plated leads. It meets JESD201 Class 1A whisker testing and complies with UL 94 V-0 flammability standards. No lead or halogen content exceeds EU Directive 2011/65/EU thresholds, and material declarations are available via Vishay's official compliance portal.
What does the "73" in GP08GHE3/73 indicate?
The "73" in GP08GHE3/73 is Vishay's preferred package code denoting ammo pack packaging: 3000 units per pack. This differs from "54", which indicates 13" diameter paper tape and reel (5500 units). Both share identical electrical and thermal specifications; the suffix affects only logistics format and is irrelevant to circuit design or soldering process. GP08GHE3/73 remains functionally and mechanically identical to GP08GHE3/54.
Can GP08GHE3/73 replace GP08JHE3/73 in a 230 VAC design?
No - GP08GHE3/73 (VRRM = 400 V) should not replace GP08JHE3/73 (VRRM = 600 V) in 230 VAC designs without verifying surge margin. While GP08GHE3/73 meets nominal 230 VAC × √2 ≈ 325 V peak, EN 61000-4-5 specifies 2 kV line-to-line surges. GP08JHE3/73 provides essential headroom; substituting GP08GHE3/73 risks reverse breakdown during transients. Always validate with worst-case surge testing before substitution.
What is the typical reverse recovery time (trr) of GP08GHE3/73 and how is it measured?
The typical reverse recovery time (trr) of GP08GHE3/73 is 2.0 μs, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per Vishay's datasheet. This value reflects the time required for minority carriers to clear after forward conduction ceases - critical for minimizing switching loss in converters. Unlike ultrafast diodes, GP08GHE3/73 is not optimized for <100 ns trr; its 2.0 μs suits 50–100 kHz applications but not MHz-range synchronous rectification.
