BYG20G-M3/TR

Overview

The BYG20G-M3/TR is a surface-mount avalanche rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage (Vr) of 400 V and an average forward rectified current (Io) of 1.5 A. The device utilizes a DO-214AC (SMA) package and exhibits a fast reverse recovery time (trr) of 75 ns, classifying it as a high-speed recovery diode with soft recovery characteristics. Forward voltage (Vf) is specified at 1.4 V when conducting 1.5 A. Reverse leakage current is limited to 1 µA at the maximum rated voltage of 400 V. The component supports a junction operating temperature range from -55°C to +150°C.

Feature Summary

• Incorporates glass passivated junction technology for enhanced reliability
• Designed with avalanche capability for robust operation under transient conditions
• Exhibits soft recovery characteristics to minimize switching noise
• Provides low reverse leakage current for efficient power management

Applications

• High-frequency switching power supplies
• Fast recovery rectification in AC/DC converters
• Inductive load protection circuits
• General-purpose high-speed rectification applications

Procurement Notes

Verify that the ordering suffix matches the required packaging format, as the base part number may be available in different tape and reel configurations or cut tapes. Confirm RoHS compliance status through the official datasheet, as environmental designations can vary between manufacturing batches or specific sub-models. Ensure the supplier provides traceable documentation confirming the component originates directly from Vishay General Semiconductor - Diodes Division to guarantee authenticity and performance specifications.

Selection Notes

Select this component when circuit requirements demand a 400 V blocking voltage combined with a 1.5 A continuous current rating in a compact surface-mount footprint. The 75 ns reverse recovery time makes it suitable for frequencies exceeding standard rectifier capabilities but potentially lower than ultra-fast alternatives. Consider the DO-214AC package dimensions for PCB layout constraints and verify thermal management needs given the 150°C maximum junction temperature limit.

Part Context

This device belongs to the BYG20 series of fast recovery avalanche rectifiers from Vishay. The 'M3' suffix typically indicates lead-free and RoHS compliance, while '/TR' denotes the Tape and Reel packaging format. This series is engineered for applications requiring reliable performance in harsh electrical environments, leveraging advanced silicon planar technology to achieve consistent electrical characteristics across production lots.

Replacement Considerations

Publicly confirmed substitute part numbers are not explicitly listed in the provided source material. Engineers should consult official cross-reference tools or contact Vishay technical support for verified equivalents that match the 400V, 1.5A, 75ns trr, and DO-214AC package specifications.
