AS1FMHM3/H

Overview

The AS1FMHM3/H is a standard avalanche surface-mount rectifier manufactured by Vishay General Semiconductor. It features a single circuit configuration within the SMF (DO-219AB) package. The device supports a maximum repetitive peak reverse voltage of 1000 V and a maximum DC forward current of 1.5 A. Peak forward surge current capability is rated at 30 A, with non-repetitive avalanche energy handling up to 20 mJ. Electrical characteristics include a typical instantaneous forward voltage of 0.84 V at 1 A and 125 °C, and a typical reverse recovery time of 1.3 μs. Operating junction and storage temperatures range from -55 °C to +175 °C.

Feature Summary

Glass passivated pellet chip junction for enhanced reliability
AEC-Q101 qualified for automotive applications
Compatible with automated placement processes
Low profile package design

Applications

General purpose rectification in power supplies
Inverter circuits
Converter topologies
Freewheeling diodes in consumer electronics
Telecommunication equipment

Procurement Notes

Verify that the specific part number matches the required automotive grade designation. Confirm compliance with RoHS standards and halogen-free material requirements as specified in the datasheet. Ensure ordering suffixes align with the desired packaging quantity and delivery mode. Validate that the component meets JESD 201 class 2 whisker test criteria before final procurement decisions.

Selection Notes

Select this component when high reverse voltage blocking capability is required in a compact surface-mount form factor. Consider the thermal resistance values for heat dissipation planning in enclosed environments. Evaluate the avalanche energy rating against potential transient conditions in the target circuit. Verify compatibility with reflow soldering profiles and moisture sensitivity level 1 requirements.

Part Context

This device belongs to the eSMP series of standard avalanche rectifiers from Vishay. It shares the SMF package outline with other variants in the family but differs in voltage ratings and specific electrical parameters. The HM3 suffix indicates an automotive-grade version compliant with AEC-Q101 standards, distinguishing it from commercial-grade counterparts.
