BYT54K-TAP

Overview

The BYT54K-TAP is a high-voltage avalanche-rated rectifier diode manufactured by Vishay General Semiconductor. It features an 800 V maximum repetitive peak reverse voltage and supports a continuous forward current of 1.25 A. The device utilizes the SOD-57 through-hole package, ensuring robust performance in demanding power applications. Designed for reliability under surge conditions, it incorporates avalanche capability to withstand energy transients without failure.

Feature Summary

• Avalanche rated for rugged operation under transient voltage stress
• High voltage blocking capability suitable for industrial power supplies
• Through-hole SOD-57 package for reliable mechanical mounting

Applications

• Industrial power supply circuits
• High voltage rectification stages
• Surge protection interfaces

Procurement Notes

Verify the specific suffix 'TAP' corresponds to the tape-and-reel packaging format required for your assembly line. Confirm that the avalanche rating aligns with your circuit's transient energy requirements. Ensure the SOD-57 through-hole footprint matches your PCB design constraints before finalizing procurement.

Selection Notes

Select this component when high voltage isolation and avalanche robustness are critical. The 800 V rating provides significant headroom for standard industrial AC lines. Consider the thermal management capabilities of the SOD-57 package for your expected average forward current loads.

Part Context

This part belongs to Vishay's general-purpose high-voltage diode lineup. It shares the SOD-57 form factor with other Vishay rectifiers but is distinguished by its specific avalanche qualification. It serves as a specialized solution for applications requiring both high voltage blocking and transient resilience.

Replacement Considerations

The UF4007 is listed as a functional substitute. Verify that the UF4007's lower voltage rating and lack of avalanche specification meet your circuit's safety margins before substitution.
