BYG22BHE3_A/H

Overview

The BYG22BHE3_A/H is a fast recovery avalanche rectifier manufactured by Vishay Semiconductors. It features a single-phase configuration housed in the DO-214AC (SMA) surface-mount package. The device supports a maximum average forward current of 2 A and withstands a repetitive peak reverse voltage of 100 V. Key electrical characteristics include a forward voltage of 1.1 V, a reverse current of 1 uA, and a maximum surge current of 35 A. The component exhibits a reverse recovery time of 25 ns and operates within a temperature range of -55 °C to +150 °C. It holds AEC-Q101 qualification for automotive reliability.

Feature Summary

• Incorporates avalanche ruggedness for enhanced robustness against transient voltage events
• Utilizes glass passivated junction technology to ensure stable performance
• Designed with soft recovery characteristics to minimize electromagnetic interference

Applications

• Automotive electronics systems requiring AEC-Q101 qualified components
• High-frequency power supply circuits utilizing surface mount assembly
• General purpose rectification in industrial equipment

Procurement Notes

Verify the specific suffix 'A/H' corresponds to the required tape and reel packaging format. Confirm that the AEC-Q101 automotive qualification status aligns with your project's reliability standards. Ensure the DO-214AC footprint matches your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a 2 A fast recovery diode with avalanche capability is required in an SMA package. The 25 ns recovery time makes it suitable for high-speed switching applications. Consider the 100 V reverse voltage rating to ensure adequate margin for your circuit's operating conditions.

Part Context

This part belongs to the BYG22 series of ultrafast avalanche rectifiers from Vishay. The series offers various voltage ratings within the same DO-214AC package family. The HE3 designation indicates compliance with RoHS directives and absence of halogenated flame retardants.

Replacement Considerations

Consult official Vishay documentation for verified cross-reference part numbers. Do not substitute based on generic specifications alone.
