BYG22B-M3/TR

Overview

The BYG22B-M3/TR 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 repetitive peak reverse voltage of 100 V and an average forward rectified current of 2 A. The device exhibits a typical reverse recovery time of 25 ns and a maximum non-repetitive peak 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 in inductive switching environments
• Glass passivated junction construction ensuring long-term stability
• Soft recovery characteristic to minimize electromagnetic interference during switching
• Low profile surface mount design suitable for automated placement processes

Applications

• Automotive electronics systems requiring AEC-Q101 qualified components
• High frequency power supply circuits utilizing fast recovery characteristics
• Primary side rectification in isolated DC/DC converter topologies
• Free-wheeling diode applications in motor drive circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm packaging format, as variations exist between reel and cut tape configurations. Ensure the component meets the required AEC-Q101 automotive qualification standards if intended for vehicle applications. Cross-reference the DO-214AC package dimensions with your PCB footprint library to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component when a 100 V rating and 2 A continuous current capacity are required in a compact SMA package. The 25 ns reverse recovery time makes it suitable for high-frequency switching applications where standard rectifiers would exhibit excessive losses. Consider the avalanche rating if the circuit experiences significant voltage spikes or inductive kickback that exceeds standard breakdown limits.

Part Context

This part belongs to the BYG22 series of ultrafast avalanche rectifiers from Vishay. The series offers various voltage ratings while maintaining consistent current handling and package form factors. These devices are engineered for surface-mount technology, providing a low-profile alternative to through-hole rectifiers in space-constrained designs.

Replacement Considerations

Direct substitutes within the same family include BYG22BHE3_A/H, which shares identical electrical specifications and package type. Verify that any replacement maintains the AEC-Q101 qualification status if automotive compliance is mandatory.
