BYG22BHM3_A/I

Overview

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

Feature Summary

• Avalanche-rated capability for robust operation under inductive switching conditions
• Glass passivated junction structure ensuring long-term stability
• Soft recovery characteristic to minimize electromagnetic interference during switching

Applications

• Automotive electronics systems requiring AEC-Q101 qualified components
• High-frequency DC/DC converter circuits
• Free-wheeling rectification in power supply designs

Procurement Notes

Verify the specific suffix 'A/I' against the manufacturer's official datasheet to confirm packaging details and compliance status. Ensure that the ordering quantity aligns with the manufacturer's standard reel specifications. Cross-reference the component marking with the official Vishay identification guide to prevent counterfeit substitution during assembly.

Selection Notes
