AU2PKHM3_A/I

Overview

The AU2PKHM3_A/I is a fast recovery rectifier from Vishay, rated for 800 V reverse voltage and 2 A forward current. It utilizes the eSMP (SMPC/TO-277A-3) surface-mount package. Key electrical parameters include a maximum forward voltage of 2.1 V at 2 A, a peak repetitive reverse current of 270 nA, and a typical reverse recovery time of 50 ns. The device supports a maximum surge current of 30 A and operates within a junction temperature range of -55°C to +175°C. It is qualified under AEC-Q101 standards.

Feature Summary

Features avalanche capability for robust operation in inductive switching environments.
Utilizes FRED Pt technology to achieve low reverse recovery charge and minimal tail current.
Designed with an eSMP package to provide high power density and efficient thermal dissipation.

Applications

Automotive DC-DC converter circuits
High-frequency switch-mode power supplies
Free-wheeling and flyback diode applications

Procurement Notes

Verify the specific suffix against official documentation, as the provided model references an 'I' suffix while source data indicates an 'H' variant. Confirm that the ordering code matches the exact package and qualification requirements. Ensure compliance with RoHS directives and REACH regulations before finalizing procurement specifications.

Selection Notes

Select this component for designs requiring high-voltage blocking capabilities combined with fast switching speeds. The TO-277A-3 package offers a compact footprint suitable for space-constrained PCB layouts. Consider the 800 V rating for safety margins in automotive or industrial power systems where transient voltages may occur.

Part Context

This part belongs to Vishay's AU2P series of fast recovery rectifiers. These devices are engineered for high-efficiency power conversion applications.
