BYG22BHM3_A/H

Overview

The BYG22BHM3_A/H is a fast recovery avalanche rectifier manufactured by Vishay Semiconductors. It features a single configuration in a DO-214AC (SMA) surface-mount package. Key electrical parameters include a maximum average forward current of 2 A, a repetitive peak reverse voltage of 100 V, and a typical forward voltage of 1.1 V at rated current. The device exhibits a fast reverse recovery time of 25 ns with low reverse current. It supports a maximum surge current of 35 A and operates within a junction temperature range of -55°C to +150°C. The component is qualified under the AEC-Q101 automotive standard.

Feature Summary

• Avalanche-rated capability for robust operation in inductive switching environments
• Soft recovery characteristic to minimize electromagnetic interference during switching
• Glass passivated junction for enhanced environmental stability and reliability
• Compliant with RoHS directives and WEEE regulations

Applications

• Automotive electronics systems requiring AEC-Q101 qualification
• High-frequency DC-DC converter circuits
• Power factor correction stages in power supplies
• General-purpose rectification in surface-mount designs

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm package type and qualification status. Ensure the ordering part number matches the required AEC-Q101 automotive grade if applicable. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring fast switching speeds combined with avalanche ruggedness. The DO-214AC package offers a compact footprint suitable for automated placement. Consider the 2 A current rating and 100 V blocking voltage when designing for low-voltage high-current power conversion topologies.

Part Context

This device belongs to the BYG22 series of ultrafast avalanche rectifiers from Vishay. The series is designed to replace bulkier through-hole components in modern surface-mount assemblies. It shares family characteristics such as soft recovery and glass passivation but differs in specific voltage and current ratings compared to other members like the BYG22D or BYG22C.

Replacement Considerations

Compatible substitutes within the same Vishay family include BYG22AHE3_A/H and BYG22CHE3_A/H. Verify that alternative part numbers match the required 100 V reverse voltage and 2 A forward current specifications.
