BYW75TAP

Overview

The BYW75TAP is a fast recovery rectifier manufactured by Vishay Semiconductors, designed for through-hole mounting in the SOD-64 axial package. It features a maximum repetitive peak reverse voltage of 500 V and an average forward current rating of 3 A. The device exhibits a typical forward voltage drop of 1.1 V at rated current and a maximum reverse leakage current of 5 µA. Its fast recovery characteristics are defined by a maximum reverse recovery time of 200 ns, supporting high-frequency switching applications. The component withstands a maximum non-repetitive peak forward surge current of 100 A and operates within a junction temperature range from -55 °C to +175 °C.

Feature Summary

• Fast recovery performance with a maximum reverse recovery time of 200 ns for efficient high-frequency operation
• High thermal stability capable of operating at junction temperatures up to 175 °C
• Robust surge handling capability with a 100 A peak non-repetitive forward surge current rating

Applications

• High-frequency power supply circuits requiring fast rectification
• Inverter and chopper circuits in industrial motor drives
• Free-wheeling diode applications in DC-DC converters

Procurement Notes

Verify the specific suffix 'TAP' against the official Vishay datasheet to confirm packaging details, as ordering codes may indicate specific reel or ammo pack configurations. Ensure the procurement channel provides valid traceability documentation. Confirm that the SOD-64 axial lead form matches the target PCB layout requirements before finalizing orders.

Selection Notes

Select this component when a 3 A continuous current rating and 500 V blocking voltage are required in a standard axial package. The 200 ns reverse recovery time makes it suitable for general-purpose high-speed rectification where ultra-fast recovery is not critical. Compare the 1.1 V forward voltage drop against alternative Schottky options if conduction losses are a primary design constraint.

Part Context

This part belongs to the Vishay BYW series of fast recovery rectifiers, which are silicon planar epitaxial diodes optimized for demanding switching applications. The series utilizes advanced processing techniques to achieve low forward voltage and controlled reverse recovery characteristics. The BYW75 variant specifically targets medium-power applications requiring reliable performance under high thermal stress conditions.

Replacement Considerations

Consult the Vishay BYW series datasheet for direct pin-compatible alternatives such as the BYW74 or BYW76, which share similar electrical parameters but differ in voltage or current ratings. Verify that any substitute maintains the SOD-64 package dimensions and axial lead configuration to ensure mechanical compatibility.
