BYG22A-M3/TR3

Overview

The BYG22A-M3/TR3 is a silicon ultrafast avalanche rectifier diode manufactured by Vishay General Semiconductor. It features a glass passivated junction and is housed in the DO-214AC (SMA) surface-mount package. The device is designed for high-speed switching applications, offering controlled avalanche characteristics and soft recovery. It complies with RoHS directives and meets MSL level 1 standards.

Feature Summary

• Ultrafast reverse recovery time for efficient high-frequency operation
• Controlled avalanche characteristic for robustness against voltage transients
• Glass passivated junction ensuring long-term reliability
• Low forward voltage drop to minimize conduction losses

Applications

• High-frequency power supply circuits
• Free-wheeling diodes in DC-DC converters
• Snubber circuits in switch-mode power supplies
• General-purpose rectification in compact electronic devices

Procurement Notes

Verify the specific suffix TR3 indicates tape-and-reel packaging when ordering. Confirm that the -M3 designation ensures compliance with current environmental regulations. Cross-reference the full part number with official Vishay documentation to ensure compatibility with automated placement equipment requirements.

Selection Notes

Select this component for designs requiring fast switching speeds within a standard SMA footprint. Ensure the circuit voltage does not exceed the rated repetitive peak reverse voltage. Consider the thermal management capabilities of the DO-214AC package for average forward current ratings in enclosed spaces.

Part Context

This part belongs to the BYG22 series of ultrafast rectifiers from Vishay. The series includes variants with different voltage ratings, such as the BYG22B and BYG22D, sharing similar physical dimensions and electrical characteristics like reverse recovery time. The -M3 suffix typically denotes lead-free and halogen-free construction compliant with EU directives.

Replacement Considerations

Compatible substitutes include other Vishay BYG22 series parts with matching voltage ratings or equivalent ultrafast rectifiers in the DO-214AC package from other manufacturers. Verify pinout compatibility and ensure replacement parts meet the same avalanche and recovery specifications.
