AU1PDHM3/85A

Overview

The AU1PDHM3/85A is a single ultrafast 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 of 1.5 V at the rated current and a typical reverse leakage current of 1 uA. Its ultrafast recovery time is specified as 75 ns, with a peak repetitive surge current capability of 30 A. The component operates within a junction temperature range of -55 °C to +175 °C and is housed in an eSMP (DO-220AA) surface-mount package.

Feature Summary

Ultrafast recovery characteristics for high-speed switching applications
High thermal stability with extended operating temperature range up to 175 °C
Avalanche-rated construction for robustness against transient overvoltage events

Applications

High-frequency power supply circuits
DC-DC converter output rectification
Free-wheeling diodes in inductive load protection

Procurement Notes

Verify the specific suffix 'H' against the official Vishay datasheet to confirm if it denotes a distinct variant or packaging specification compared to the standard AU1PD-M3/85A part number. Ensure the ordering information matches the exact electrical parameters required for the design, particularly regarding the avalanche rating and package type.

Selection Notes

Select this component when designing circuits requiring fast recovery times and high reliability under thermal stress. The 200 V rating suits low-voltage DC conversion systems. Consider the DO-220AA footprint constraints and the need for surface-mount assembly capabilities during PCB layout planning.

Part Context

This device belongs to the AU1P series of ultrafast recovery rectifiers from Vishay. These components are engineered for efficiency in modern power electronics, offering superior performance over standard rectifiers in terms of switching speed and thermal handling within compact surface-mount packages.
