Product details
Overview
FGP50B-E3/73 from Vishay General Semiconductor is a glass-passivated ultrafast plastic rectifier diode rated for 100 V repetitive peak reverse voltage, 5.0 A average forward current, and 35 ns reverse recovery time, with 0.95 V forward voltage at 5.0 A and 5.0 μA reverse leakage at 25 °C; used in high-frequency freewheeling and output rectification in automotive DC-DC converters.
For engineers reviewing the FGP50B-E3/73 datasheet, FGP50B-E3/73 pinout, FGP50B-E3/73 application, or FGP50B-E3/73 equivalent, key selection criteria include ultrafast switching (35 ns trr), AEC-Q101 qualification, low VF (0.95 V), thermal robustness (TJ max = 175 °C), and GP20 package compatibility with automated SMT and through-hole assembly.
Technical Context
This device implements a SUPERECTIFIER® structure with cavity-free glass-passivated junction to ensure high reliability under thermal cycling and humidity stress. Its ultrafast recovery (35 ns) enables efficient operation in 100–500 kHz switching topologies without snubber circuits.
The GP20 package features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, supports solder dip up to 275 °C for 10 s, and meets UL 94 V-0 flammability rating; polarity is marked by cathode band.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay FGP50C-E3/73 | Higher VRRM (150 V) and VRMS (105 V); identical trr (35 ns), VF (0.95 V), and package | Required where input transients exceed 100 V, e.g., 48 V systems with >100 V load dump | Select FGP50C-E3/73 when system-level transient immunity requires ≥150 V blocking |
| ON Semiconductor MUR5100CT-E3/45 | Dual common-cathode configuration; 100 V VRRM, 50 ns trr, 1.25 V VF at 5 A, TO-220AC package | Requires PCB redesign due to different footprint and thermal interface; higher VF increases conduction loss | Choose only if dual-diode topology is needed and TO-220 mounting is acceptable |
Compared with FGP50C-E3/73 and MUR5100CT-E3/45, the FGP50B-E3/73 offers optimal balance of 100 V rating, ultrafast 35 ns recovery, and GP20 through-hole compatibility-making it ideal for cost-sensitive, space-constrained automotive and industrial rectifiers where 100 V blocking suffices.

FAQ
What is the maximum junction temperature rating for the FGP50B-E3/73?
The FGP50B-E3/73 has a maximum junction temperature (TJ max.) of +175 °C, enabling reliable operation in under-hood automotive environments and high-ambient industrial settings. This rating is validated per AEC-Q101 stress testing and supported by its GP20 package thermal resistance (RθJL = 20 °C/W). The FGP50B-E3/73 must be derated per the published forward current derating curve above 25 °C ambient.
Is the FGP50B-E3/73 qualified for automotive applications?
Yes, the FGP50B-E3/73 is AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 12-Dec-13. It undergoes rigorous stress testing including temperature cycling, humidity bias, and high-temperature reverse bias to meet automotive reliability standards. The "E3" suffix denotes RoHS-compliant commercial grade, while "HE3" indicates AEC-Q101 qualification-however, the FGP50B-E3/73 itself carries AEC-Q101 qualification per primary characteristics table note (1).
What does the "/73" suffix mean in FGP50B-E3/73?
The "/73" suffix in FGP50B-E3/73 specifies ammo pack packaging containing 2000 units, as defined in Vishay's ordering information table. It distinguishes packaging format from "/54" (13" paper tape and reel, 1400 units). The FGP50B-E3/73 retains identical electrical, thermal, and mechanical specifications as other FGP50B-E3 variants-only the delivery mode differs.
How does the FGP50B-E3/73 compare to standard fast recovery diodes?
The FGP50B-E3/73 delivers 35 ns reverse recovery time-significantly faster than typical fast recovery diodes (≥100 ns)-reducing switching losses and EMI in high-frequency converters. Its SUPERECTIFIER® structure also provides superior reliability versus conventional passivated diodes, especially under thermal cycling. The FGP50B-E3/73 achieves this without sacrificing forward voltage (0.95 V at 5 A), making it more efficient than many competing ultrafast devices.
What is the thermal resistance from junction to lead (RθJL) for the FGP50B-E3/73?
The FGP50B-E3/73 has a typical thermal resistance from junction to lead (RθJL) of 20 °C/W, measured at 0.375" (9.5 mm) lead length with both leads attached to heatsinks. This value enables effective heat transfer in through-hole designs where leads serve as thermal paths. For PCB-mounted operation, RθJA is 60 °C/W; actual thermal performance of the FGP50B-E3/73 depends on copper area, layer count, and airflow.
