BYG24GHM3_A/I

Overview

The BYG24GHM3_A/I is a fast recovery avalanche rectifier manufactured by Vishay Semiconductors. It features a single-phase configuration in a DO-214AC (SMB) surface-mount package. Key electrical parameters include a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current of 1.5 A. The device exhibits a typical forward voltage of 1.25 V at rated current and a maximum reverse leakage current of 1 µA. It supports a maximum non-repetitive peak forward surge current of 30 A with a reverse recovery time of 140 ns. Operating temperatures range from -55 °C to +150 °C junction temperature, and the component holds AEC-Q101 qualification for automotive applications.

Feature Summary

• Incorporates avalanche-rated capability for enhanced ruggedness against transient voltage events.
• Features fast recovery characteristics designed to minimize switching losses in high-frequency circuits.
• Constructed with low leakage current properties to improve efficiency in power conversion systems.

Applications

• Automotive electronics requiring AEC-Q101 qualified components
• High-efficiency DC/DC converter output rectification
• Freewheeling diode applications in switched-mode power supplies

Procurement Notes

Verify the specific suffix designation during procurement, as variations such as _A/H or _A/I may indicate differences in packaging or tape-and-reel specifications rather than functional changes. Confirm that the required quantity aligns with standard reel sizes provided by the manufacturer. Ensure compliance with RoHS directives and check for any specific handling requirements associated with surface-mount avalanche rectifiers.

Selection Notes

Select this component when designing circuits that demand both fast switching speeds and robustness against inductive kickback voltages. The 400 V rating suits medium-voltage applications, while the 1.5 A current capacity fits moderate power levels. Consider the SMB package for space-constrained PCB layouts. Verify thermal management needs given the 150 °C maximum junction temperature limit.

Part Context

This part belongs to Vishay's BYG series of glass-passivated surface-mount fast recovery rectifiers. The series is engineered for general-purpose and high-efficiency applications where small footprint and high reliability are critical. The avalanche variant specifically addresses scenarios requiring tolerance to repeated avalanche energy stress without degradation.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with other Vishay SMB-packaged 400V 1.5A fast recovery diodes only if electrical parameters match exactly and avalanche capability is not a strict requirement.
