BYT51K-TR

Overview

The BYT51K-TR is an avalanche-rated rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 800 V and an average forward rectified current of 1.5 A. The device utilizes the SOD-57 (DO-214AA) surface-mount package. It is designed for high-reliability applications requiring robust surge handling capabilities, characterized by a non-repetitive peak forward surge current of 50 A.

Feature Summary

• Avalanche rated construction for enhanced ruggedness
• Surface-mount SOD-57 package design
• High surge current capability

Applications

• General purpose rectification in power supplies
• Protection circuits requiring avalanche tolerance
• Industrial control systems

Procurement Notes

Verify the specific suffix '-TR' indicates tape and reel packaging when ordering. Confirm that the 800V rating aligns with system voltage requirements. Ensure the SOD-57 footprint matches the PCB layout. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this component where high reverse voltage blocking and moderate current handling are required in a compact surface-mount form factor. The avalanche rating distinguishes it from standard rectifiers, making it suitable for environments with potential inductive load switching or voltage transients.

Part Context

This part belongs to Vishay's discrete semiconductor diode portfolio. It is distinct from the BYT51J variant, which typically offers a lower voltage rating of 600 V. The BYT51 series provides a balance of performance and size for modern electronic designs.

Replacement Considerations

The BYT51J-TR is a related variant within the same family but differs in voltage rating. Verify electrical parameters before substitution. No other direct public substitute part numbers are confirmed.
