BYG22A-M3/TR

Overview

The BYG22A-M3/TR is a silicon ultrafast avalanche rectifier diode manufactured by Vishay General Semiconductor. It features a controlled avalanche characteristic and is housed in the DO-214AC (SMA) surface-mount package. The device is designed for high-speed switching applications, offering low reverse current and soft recovery characteristics. It meets MSL level 1 standards per J-STD-020 with a maximum peak reflow temperature of 260 °C. The component is compliant with RoHS Directive 2002/95/EC and WEEE 2002/96/EC.

Feature Summary

• Controlled avalanche characteristic for robust operation
• Glass passivated junction for enhanced reliability
• Ultra-fast reverse recovery time for high-speed switching
• Soft recovery characteristic to minimize electromagnetic interference

Applications

• Primary side rectification in switch-mode power supplies
• High-frequency DC-DC converter circuits
• Automotive electronics requiring AEC-Q101 qualification

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm packaging type and reel specifications. Ensure the ordered part matches the required voltage rating within the BYG22 series. Confirm RoHS compliance status and AEC-Q101 automotive qualification requirements prior to procurement. Cross-reference the manufacturer date code with project timelines.

Selection Notes

Select this component for applications requiring fast recovery and avalanche ruggedness in a compact SMA package. Consider the thermal management capabilities of the DO-214AC footprint. Evaluate the forward voltage drop and reverse leakage current against circuit efficiency targets. Verify compatibility with automated placement equipment due to the low profile design.

Part Context

This diode belongs to the BYG22 series of ultrafast SMD rectifiers from Vishay. The series includes variants with different voltage ratings, such as the BYG22B (100V), BYG22C (200V), and BYG22D (400V). All members share similar physical dimensions and electrical characteristics regarding recovery time and avalanche capability, differing primarily in their repetitive peak reverse voltage limits.

Replacement Considerations

Compatible substitutes include other Vishay BYG22 series parts like BYG22B-M3/TR or BYG22C-M3/TR if voltage ratings align. External equivalents must match the DO-214AC package, 2A average forward current, and ultrafast recovery specifications. Verify that alternative components also offer controlled avalanche characteristics if surge protection is required.
