FEP16GTHE3/45

Diode Arrays Overview

The FEP16GTHE3/45 is a dual common cathode fast recovery rectifier manufactured by Vishay General Semiconductor. It features a peak repetitive reverse voltage of 400 V and an average forward current rating of 16 A. The device exhibits a maximum reverse recovery time of 50 ns and a peak non-repetitive forward surge current capacity of 125 A. Forward voltage is specified at 1.3 V when conducting 16 A, with a maximum reverse leakage current of 10 µA at 400 V. It utilizes a TO-220AB package for through-hole mounting.

Diode Arrays Feature Summary

• Dual common cathode configuration integrates two diodes in a single package to reduce component count.
• Fast recovery characteristics enable high efficiency and reduced switching losses in high-frequency applications.
• Glass passivated junction construction ensures stability under thermal stress and mechanical shock.

Diode Arrays Applications

• High-frequency DC-to-DC converter output rectification
• Free-wheeling diode implementation in motor drive circuits
• Inductive load protection in power supply designs

Diode Arrays Procurement Notes

Verify the specific suffix 'GT' against procurement requirements, as it denotes the dual common cathode variant within the FEP series. Confirm that the TO-220AB package dimensions align with the target PCB footprint. Ensure compliance with RoHS directives if environmental regulations apply to the final assembly. Cross-reference the manufacturer's latest datasheet to validate electrical parameters before finalizing the bill of materials.

Diode Arrays Selection Notes

Select this component when circuit topology requires a shared cathode connection for two independent rectification paths. The 16 A current rating supports moderate power levels, while the 400 V blocking capability suits standard industrial voltage rails. The 50 ns recovery time is suitable for frequencies exceeding typical low-frequency rectification needs. Evaluate thermal management requirements based on the 1.3 V forward drop at full load conditions.

Diode Arrays Part Context

This part belongs to the FEP16xT family of Vishay fast recovery rectifiers. Variants such as FEP16AT, FEP16BT, and FEP16CT differ primarily in their reverse voltage ratings, ranging from 50 V to 150 V. The FEP16HT-E3/45 offers a higher 500 V rating, while the FES16GT-E3/45 represents a similar current-rated but distinct product line. All variants share the same physical package and general structural design principles.

Diode Arrays Replacement Considerations

Direct substitutes include the FEP16GT-E3/45, which shares identical electrical specifications and pinout configuration. Designers should verify that any alternative dual common cathode rectifier meets or exceeds the 16 A continuous current and 400 V reverse voltage requirements to maintain circuit integrity.
