Product details
Overview
FEPF16GT-E3/45 from Vishay General Semiconductor is a dual common cathode ultrafast plastic rectifier in TO-220AB package, rated for 500 V repetitive peak reverse voltage (VRRM), 16 A average forward current per diode (IF(AV)), and 35 ns reverse recovery time (trr). It delivers low forward voltage drop (1.50 V at 8.0 A) and high surge capability (200 A IFSM), targeting high-frequency switching power supplies and DC/DC converters.
For engineers reviewing the FEPF16GT-E3/45 datasheet, FEPF16GT-E3/45 pinout, FEPF16GT-E3/45 application, or FEPF16GT-E3/45 equivalent, key selection criteria include VRRM = 500 V, trr = 35 ns, dual common-cathode configuration, TO-220AB thermal resistance (RθJC = 2.2 °C/W per diode), and RoHS-compliant commercial-grade construction.
Technical Context
This device integrates two ultrafast silicon junction diodes in a single TO-220AB thermally optimized package with glass-passivated chips. Its 35 ns recovery time and 1.50 V forward voltage at 8.0 A enable high-efficiency operation in 100–500 kHz SMPS topologies where switching losses must be minimized.
The dual common-cathode topology simplifies PCB layout for center-tapped transformer secondary rectification and freewheeling paths. With 2.2 °C/W junction-to-case thermal resistance and 150 °C maximum junction temperature, it supports continuous conduction mode operation under forced-air or heatsink-cooled conditions.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1605CW | 500 V VRRM, 35 ns trr, but 1.75 V VF @ 8 A and RθJC = 3.0 °C/W | Higher conduction loss and thermal resistance limit usable current to ≤12 A in same heatsink | Select when STMicroelectronics supply chain alignment is required; verify thermal margin at full load |
| IXYS MUR1650CT | 500 V VRRM, 35 ns trr, 1.55 V VF, but TO-220AC package (non-isolated tab) | Requires insulating washer for heatsink mounting; lower creepage distance limits use in reinforced insulation designs | Prefer when isolation between tab and heatsink is not required; confirm safety spacing compliance per IEC 62368-1 |

FAQ
What is the maximum junction temperature rating for FEPF16GT-E3/45?
The FEPF16GT-E3/45 has a maximum junction temperature (TJ) of +150 °C, verified per Vishay's thermal characterization data. This rating allows continuous operation in ambient temperatures up to +85 °C when mounted on a heatsink providing ≤2.2 °C/W thermal resistance from junction to ambient. Derating curves in the official datasheet (Document Number: 88596) define safe operating area boundaries at elevated case temperatures.
Is FEPF16GT-E3/45 RoHS-compliant and lead-free?
Yes, the FEPF16GT-E3/45 carries the "E3" suffix, indicating full compliance with the EU RoHS Directive 2011/65/EU and exemption 7a. It is lead-free, with matte tin-plated leads meeting J-STD-002 solderability requirements and passing JESD201 Class 1A whisker testing. No lead or cadmium is present above threshold limits, and the molding compound meets UL 94 V-0 flammability standards.
What is the reverse recovery time (trr) specification for FEPF16GT-E3/45 and how is it measured?
The FEPF16GT-E3/45 has a maximum reverse recovery time (trr) of 35 ns, measured under standardized conditions: IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per JEDEC test method JESD24-11. This value reflects the time required for minority carriers to clear after forward conduction, directly impacting switching loss in high-frequency converters. The 35 ns figure applies to both diodes in the dual package.
Can FEPF16GT-E3/45 be used as a direct replacement for FEPF16DT in existing designs?
No-FEPF16GT-E3/45 is not a direct replacement for FEPF16DT. While both share the same TO-220AB package and dual common-cathode configuration, the FEPF16GT-E3/45 is rated for 500 V VRRM and 1.50 V VF, whereas FEPF16DT is rated for 200 V VRRM and 1.30 V VF. Substituting without verifying voltage margin and thermal performance may result in premature failure under 400 V bus conditions.
Does FEPF16GT-E3/45 have AEC-Q101 qualification?
No, the FEPF16GT-E3/45 is not AEC-Q101 qualified. It carries the "E3" commercial-grade suffix. For automotive applications requiring AEC-Q101, Vishay offers the HM3-suffixed variant (e.g., FEPF16GTHM3/45) in D2PAK (TO-263AB) only-not in TO-220AB. The FEPF16GT-E3/45 is intended for industrial, computing, and telecom power systems where automotive qualification is not mandated.
