Product details
Overview
GP15GHE3/73 from Vishay General Semiconductor is a glass passivated junction plastic rectifier diode in DO-15 package, rated for 400 V repetitive peak reverse voltage (VRRM), 1.5 A average forward current (IF(AV)), and 1.1 V forward voltage drop at 1.5 A. It delivers low leakage (5.0 μA at 25 °C), fast reverse recovery (3.5 μs), and operates up to 175 °C junction temperature-used as a freewheeling diode in offline AC/DC adapters and DC-DC converter output stages.
For engineers reviewing the GP15GHE3/73 datasheet, GP15GHE3/73 pinout, GP15GHE3/73 application, or GP15GHE3/73 equivalent, key selection factors include its 400 V VRRM rating, DO-15 mechanical compatibility, 50 A surge capability, thermal resistance (RθJL = 20 °C/W), and RoHS-compliant matte tin-plated leads per J-STD-002.
Technical Context
This device implements a single silicon PN junction with cavity-free glass passivation, enabling high reliability in continuous conduction mode rectification. Its Superectifier® structure minimizes leakage and improves thermal stability under sustained load conditions.
Designed for line-frequency and low-frequency switching applications, it supports 60 Hz resistive/inductive loads with derated current above 55 °C ambient and withstands 8.3 ms half-sine surge currents up to 50 A without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - blocks up to 400 V repetitive reverse voltage in bridge or freewheeling configurations |
| IF(AV) | 1.5 A at 55 °C with 0.375" lead length - defines continuous DC output current capability in power supply designs |
| VF | 1.1 V at 1.5 A - determines conduction loss and thermal dissipation in rectifier stage |
| trr | 3.5 μs - enables use in 20–50 kHz flyback and forward converters without excessive switching loss |
| IR | 5.0 μA at 25 °C - ensures minimal standby power loss in low-power adapter standby modes |
| TJ max. | 175 °C - allows operation in sealed enclosures or high-ambient industrial environments |
| RθJL | 20 °C/W - indicates efficient heat transfer from junction to lead, supporting PCB-mount thermal design |

Applications
| AC/DC Adapter Output Rectification | DC-DC Converter Freewheeling Diode |
|---|---|
Use Scenario: Secondary-side rectification in 5–24 V, 10–30 W offline flyback adapters. IC Role / Device Role / Timing Role: Unidirectional current valve converting transformer secondary AC to regulated DC output. Use Value: 1.1 V VF minimizes conduction loss at 1.5 A load; 400 V VRRM accommodates reflected voltage spikes in discontinuous conduction mode. | Use Scenario: Freewheeling path in 12 V input, 3.3/5 V output buck converters for set-top boxes. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path during high-side MOSFET off-time. Use Value: 3.5 μs trr prevents cross-conduction loss; DO-15 footprint enables manual repair and cost-effective through-hole assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4007G-E3/54 | VRRM = 1000 V, VF = 1.1 V, IF(AV) = 1.0 A, DO-41 package | Higher voltage rating but lower current; smaller DO-41 footprint limits thermal mass | Prefer when >600 V blocking required and board space is constrained |
| GP15JHE3/73 | VRRM = 600 V, identical package, pinout, and thermal specs | Same mechanical fit but higher reverse voltage margin for 230 VAC input designs | Select when designing for universal input (90–264 VAC) with safety margin on VRRM |
Compared with 1N4007G-E3/54 and GP15JHE3/73, GP15GHE3/73 offers optimal balance of 400 V VRRM, 1.5 A current, and DO-15 thermal performance-making it preferred for 115 VAC-only or 24–48 VDC-input systems where surge robustness and thermal derating are critical.

FAQ
What is the maximum junction temperature rating for GP15GHE3/73?
The GP15GHE3/73 has a maximum junction temperature (TJ max.) of +175 °C, verified per Vishay Document Number 88638. This rating enables reliable operation in enclosed or high-ambient environments such as sealed power adapters or industrial control cabinets. Derating curves in the GP15GHE3/73 datasheet specify usable current versus ambient temperature, with full 1.5 A IF(AV) permitted only up to 55 °C ambient using 0.375" lead length.
Is GP15GHE3/73 RoHS-compliant and lead-free?
Yes, GP15GHE3/73 is RoHS-compliant and lead-free. The "E3" suffix denotes Vishay's commercial-grade, RoHS-compliant construction with matte tin-plated leads that meet J-STD-002 solderability requirements. It also passes JESD 201 Class 1A whisker testing, confirming long-term termination reliability without lead content.
What does the "73" in GP15GHE3/73 indicate?
The "73" in GP15GHE3/73 is Vishay's packaging code specifying ammo pack delivery: 2000 units per pack. This contrasts with "54", which denotes 4000 units on 13" paper tape and reel. Both share identical electrical and mechanical specifications; only packaging format and quantity differ-critical for SMT line feed compatibility or manual assembly logistics.
Can GP15GHE3/73 replace GP15GHE3/54 in existing designs?
Yes, GP15GHE3/73 is functionally and mechanically identical to GP15GHE3/54-same die, DO-15 package, electrical specs, and thermal performance. Only packaging differs: GP15GHE3/73 ships in ammo packs (2000 pcs), while GP15GHE3/54 uses tape-and-reel (4000 pcs). No PCB or schematic changes are needed when substituting GP15GHE3/73 into designs originally specified with GP15GHE3/54.
Why is GP15GHE3/73 marked "Not for New Designs"?
Vishay marks GP15GHE3/73 "Not for New Designs" because newer surface-mount alternatives (e.g., SMA/SMB packages) offer higher power density and automated assembly efficiency. However, GP15GHE3/73 remains fully supported for legacy production, repair, and cost-sensitive through-hole applications where DO-15's mechanical robustness and hand-solderability are advantageous.
