AU1FDHM3/I

Overview

The AU1FDHM3/I is a single ultra-fast recovery rectifier manufactured by Vishay Semiconductors. It features a 200 V reverse voltage rating and supports a continuous forward current of 1 A. The device exhibits a maximum forward voltage drop of 1.5 V and a peak surge current capability of 30 A. Its ultra-fast recovery time is specified at 75 ns with a low reverse leakage current of 1 uA. Designed for surface-mount applications, it utilizes the DO-219AB-2 (SMF) package. The component operates reliably within a junction temperature range from -55 °C to +175 °C.

Feature Summary

Ultra-fast recovery characteristics suitable for high-frequency switching applications
Glass passivated chip junction for enhanced reliability
Controlled avalanche breakdown characteristics

Applications

High-frequency power supply circuits
DC-DC converter output rectification
Free-wheeling diode applications in inductive loads

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm exact electrical tolerances and packaging details. Ensure the ordering part number matches the required package style and tape-and-reel specifications. Cross-reference the manufacturer's latest datasheet for any updates on environmental compliance or material declarations prior to final procurement.

Selection Notes

Select this component when an ultra-fast recovery time is critical for minimizing switching losses in low-voltage, high-frequency circuits. The 1 A current rating and 200 V blocking voltage define its operational limits. Consider the SMF package dimensions for PCB layout constraints and verify thermal management requirements for the intended operating environment.

Part Context

This component belongs to the AU1FD series of ultra-fast recovery rectifiers from Vishay. These devices are engineered for compact surface-mount designs requiring fast switching speeds. The series typically offers controlled avalanche ruggedness and low leakage currents, making them distinct from standard recovery diodes in efficiency-sensitive power conversion topologies.
