BYG22BHE3_A/I

Overview

The BYG22BHE3_A/I is a fast recovery avalanche rectifier manufactured by Vishay Semiconductors. It features an average forward current of 2 A and a repetitive peak reverse voltage of 100 V. The device exhibits a maximum reverse recovery time of 25 ns and a forward voltage of 1.1 V at rated current. It operates within a junction temperature range of -55 °C to +150 °C and has a maximum surge current rating of 35 A. The component utilizes a DO-214AC (SMA) surface-mount package and holds AEC-Q101 qualification for automotive applications.

Feature Summary

• Avalanche capability allows operation in inductive switching modes without failure
• Glass passivated junction provides robust protection against mechanical stress
• Soft recovery characteristic minimizes electromagnetic interference during switching
• Ultra-fast reverse recovery time supports high-frequency power conversion

Applications

• Automotive electronics systems requiring AEC-Q101 qualified components
• High-frequency switch-mode power supplies
• Free-wheeling diodes in inductive load circuits
• Polarity protection circuits in DC power inputs

Procurement Notes

Verify the specific suffix 'A/I' matches the required tape-and-reel packaging configuration, as suffixes often denote distinct handling or shipping formats rather than electrical changes. Confirm that the AEC-Q101 qualification status is explicitly stated for this exact part number variant in the official datasheet before finalizing procurement specifications.

Selection Notes

Select this component when a 2 A fast recovery rectifier with avalanche ruggedness is required in a compact SMA package. Ensure the circuit design accounts for the 100 V reverse voltage limit and the 25 ns recovery time constraints. Verify thermal management requirements align with the specified operating temperature range and forward voltage characteristics under expected load conditions.

Part Context

This device belongs to the BYG22 series of ultrafast avalanche rectifiers from Vishay. The series is designed for surface-mount applications where space efficiency and high-speed switching performance are critical. The eSMP trademark indicates specific manufacturing standards associated with this product line.

Replacement Considerations

Cross-reference with other Vishay BYG22B variants such as BYG22B-HE3/TR3 for identical electrical specifications but potentially different packaging formats. Ensure any substitute maintains the DO-214AC footprint and AEC-Q101 qualification if automotive compliance is mandatory.
