BYG20J-M3/TR

Overview

The BYG20J-M3/TR is an ultrafast avalanche rectifier from Vishay General Semiconductor, rated for a maximum repetitive peak reverse voltage of 600 V and an average forward current of 1.5 A. It features a 75 ns maximum reverse recovery time and supports a 30 A peak forward surge current. The device operates within a junction temperature range of -55 °C to +150 °C and exhibits a maximum instantaneous forward voltage of 1.4 V at 1.5 A. Packaged in the low-profile SMA (DO-214AC) surface-mount format with matte tin-plated leads, it is designed for automated placement.

Feature Summary

• Ultrafast reverse recovery characteristics suitable for high-frequency applications
• Avalanche-rated capability for non-repetitive pulse energy absorption
• Glass passivated pellet chip junction for enhanced reliability
• Halogen-free and RoHS-compliant commercial grade construction

Applications

• High frequency rectification in power supplies
• Inverter and converter circuits
• Freewheeling diodes for consumer electronics
• Automotive electronic systems
• Telecommunication equipment

Procurement Notes

Verify that the specific ordering code matches the required halogen-free M3 suffix and TR reel quantity. Confirm compliance with JESD 201 class 2 whisker test requirements if applicable. Ensure the package type aligns with automated placement specifications. Validate thermal resistance parameters against the target circuit design constraints before finalizing procurement.

Selection Notes

Select this component when a 600 V blocking capability and 1.5 A continuous current rating are required in a compact surface-mount form factor. The 75 ns reverse recovery time makes it appropriate for high-speed switching environments. Consider the avalanche rating for inductive load switching scenarios where non-repetitive pulse energy dissipation is necessary.

Part Context

This part belongs to the BYG20 series of ultrafast SMD rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different voltage ratings, such as 200 V and 400 V options. All models share identical physical dimensions and electrical characteristics except for the maximum repetitive peak reverse voltage specification.

Replacement Considerations

Cross-reference with BYG20J-E3/TR for standard commercial grade equivalents. Verify compatibility with BYG20JHE3_A/H or BYG20JHM3_A/H if automotive AEC-Q101 qualification is required.
