BYG20D-M3/TR

Overview

The BYG20D-M3/TR is a fast silicon mesa surface-mount rectifier diode manufactured by Vishay General Semiconductor. It utilizes glass passivated junctions and features controlled avalanche characteristics suitable for high-reliability applications. The device is housed in the DO-214AC (SMA) package, designed for automated placement. Key electrical ratings include a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current of 1.5 A. The component exhibits a typical reverse recovery time of 75 ns and a maximum forward voltage of 1.3 V at rated current. It operates within a junction temperature range of -55°C to 150°C.

Feature Summary

• Glass passivated junction provides robust protection against voltage transients and ensures low reverse leakage current.
• Controlled avalanche characteristics allow safe operation in hard-switching applications without secondary breakdown risks.
• Soft recovery characteristics minimize electromagnetic interference (EMI) during switching transitions.

Applications

• General purpose rectification in power supplies
• Freewheeling diodes in inverters and converters
• Consumer, automotive, and telecommunication equipment

Procurement Notes

Verify the specific suffix 'M3' confirms RoHS compliance and halogen-free status as per Vishay standards. Confirm the '/TR' designation indicates tape-and-reel packaging rather than cut tape or Digi-Reel options. Ensure the base part number BYG20D matches the required 200V rating, as other variants in the series offer different voltage levels. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing specifications.

Selection Notes

Select this component when a fast recovery rectifier with avalanche capability is required in a compact SMA package. The 1.5A current rating suits moderate power applications where space is constrained. Consider the 75ns reverse recovery time for efficiency in higher frequency circuits compared to standard rectifiers. Verify thermal management requirements given the 150°C maximum junction temperature limit.

Part Context

This part belongs to the BYG20 series of fast silicon mesa SMD rectifiers from Vishay. The series covers voltage ratings from 200V to 1600V with consistent 1.5A current handling. The DO-214AC package is widely used in surface-mount technology for its reliability and small footprint. The M3 suffix typically denotes environmental compliance, while TR indicates reel packaging for high-volume assembly.
