BYW73-TAP

Overview

The BYW73-TAP is a fast avalanche sinterglass diode manufactured by Vishay General Semiconductor - Diodes Division. It features a hermetically sealed SOD-64 package with plated axial leads. The device provides a repetitive peak reverse voltage of 300 V and an average forward current rating of 3 A. Key electrical characteristics include a maximum reverse recovery time of 200 ns, a typical forward voltage of 0.95 V at 3 A, and a non-repetitive reverse avalanche energy capability of 10 mJ. The component operates within a junction temperature range of -55 °C to +175 °C.

Feature Summary

• Fast avalanche sinterglass construction for high reliability
• Hermetically sealed glass passivated junction
• Soft recovery characteristics suitable for switching applications

Applications

• TV-line output circuits
• Switch mode power supplies

Procurement Notes

Verify the specific ordering code BYW73-TAP against official Vishay documentation to confirm packaging details. This designation indicates a tape and reel configuration containing 2500 units per ammopack. Ensure that the required minimum order quantity aligns with your production needs before finalizing procurement. Confirm compliance with RoHS standards as specified in the datasheet.

Selection Notes

Select this component when a 300 V reverse voltage rating and 3 A average forward current are required. The SOD-64 package is suitable for through-hole mounting. Consider the 200 ns reverse recovery time for high-frequency switching requirements. Verify thermal management capabilities based on the specified junction-to-ambient thermal resistance values for your specific application environment.

Part Context

This part belongs to the BYW72-BYW76 series of fast avalanche sinterglass diodes from Vishay Semiconductors. The series differentiates models primarily by their repetitive peak reverse voltage ratings, which range from 200 V to 600 V. All variants share the same SOD-64 package and 3 A average forward current capability, offering design flexibility for various voltage levels while maintaining consistent mechanical and thermal properties.

Replacement Considerations

Direct substitutes within the same Vishay series include BYW72 (200 V), BYW74 (400 V), BYW75 (500 V), and BYW76 (600 V). Selection depends on whether the circuit requires a lower or higher voltage rating than the 300 V provided by the BYW73. Ensure any replacement maintains the SOD-64 package and similar electrical characteristics such as reverse recovery time and forward current capacity.
