BYT56A-TR

Overview

The BYT56A-TR is a fast silicon mesa rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features an avalanche ruggedness rating and is housed in the SOD-64 axial through-hole package. The device supports a maximum repetitive peak reverse voltage of 50 V and an average forward rectified current of 3 A. Key electrical characteristics include a maximum forward voltage of 1.4 V at 3 A, a reverse recovery time of less than or equal to 500 ns for currents greater than 200 mA, and a peak forward surge current capability of 80 A. The component operates within a junction temperature range of -55°C to 175°C.

Feature Summary

• Fast recovery performance suitable for high-frequency switching applications
• Avalanche rated construction for enhanced robustness against transient overvoltages
• High thermal stability with extended operating junction temperature range

Applications

• General purpose rectification in power supplies
• Freewheeling diodes in inductive load circuits
• Protection circuits requiring avalanche energy handling

Procurement Notes

Verify the specific suffix 'TR' corresponds to tape and reel packaging requirements for automated assembly lines. Confirm that the 50V voltage rating aligns with the circuit's peak inverse voltage demands. Ensure the SOD-64 axial lead form factor fits the designated PCB footprint. Cross-reference the manufacturer datasheet for any recent changes in marking codes or environmental compliance declarations prior to final procurement authorization.

Selection Notes

Select this component when a 50V blocking voltage and 3A continuous current capacity are required in a compact axial package. The fast recovery characteristic makes it appropriate for frequencies where standard rectifiers would exhibit excessive losses. Consider the avalanche rating if the application involves significant inductive kickback or transient spikes that exceed normal operating voltages but remain within the single pulse avalanche energy limits defined in the datasheet.

Part Context

The BYT56 series represents Vishay's fast silicon mesa rectifiers designed for general-purpose applications. The BYT56A variant specifically denotes the 50V rating within this family, distinguishing it from higher voltage options like the BYT56B (100V) or BYT56M (1000V). These devices utilize mesa technology to achieve fast recovery times while maintaining reliability in through-hole mounting configurations common in legacy and industrial electronics.

Replacement Considerations

Direct substitutes must match the 50V VR, 3A IF, and SOD-64 package. Verify equivalent reverse recovery time and avalanche ratings. Generic replacements may differ in thermal resistance or surge current capabilities.
