FESF16DTHE3_A/P

Single Diodes Overview

The FESF16DTHE3_A/P is a standard rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a 16 A average forward rectified current rating and a 300 V repetitive peak reverse voltage capability. The device utilizes a fast recovery technology with a typical reverse recovery time of 35 ns. It is housed in a TO-263AB (D2PAK) surface-mount package, designed for high-efficiency power conversion applications requiring robust performance under thermal stress.

Single Diodes Feature Summary

• Fast recovery characteristics enable efficient switching in high-frequency circuits
• Low forward voltage drop contributes to reduced conduction losses
• Robust construction supports high surge current handling capabilities

Single Diodes Applications

• High-frequency DC-DC converters
• Free-wheeling diodes in synchronous rectification topologies
• Power supply output rectification

Single Diodes Procurement Notes

Verify the exact suffix against official Vishay documentation, as variations such as _A/P may indicate specific tape-and-reel configurations or regional compliance markings that do not alter electrical function but affect logistics. Confirm end-of-life status through authorized distributors, as this component family may be subject to discontinuation notices. Ensure compatibility with automated pick-and-place equipment given the D2PAK footprint requirements.

Single Diodes Selection Notes

Select this component when designing systems requiring a balance between high current capacity and fast switching speeds. The 300 V rating provides sufficient margin for common 24 V and 48 V bus architectures while minimizing leakage current. Consider the thermal resistance of the TO-263AB package and ensure adequate PCB copper area for heat dissipation to maintain junction temperature within safe operating limits during continuous operation.

Single Diodes Part Context

This part belongs to the FESB/FESF series of fast recovery rectifiers from Vishay. These components are engineered for use in hard-switched and soft-switched power supplies. The series offers various voltage ratings to suit different input/output requirements, maintaining consistent current handling and recovery time specifications across the range to simplify BOM management for multi-voltage product lines.

Single Diodes Replacement Considerations

Cross-reference with FESB16FTHE3/45 for identical electrical specifications in alternative packaging. Verify pinout compatibility before substitution. Check for updated RoHS compliance statements if environmental regulations have changed since the original datasheet publication.
