BYW172F-TAP

Overview

The BYW172F-TAP is a fast avalanche sinterglass diode manufactured by Vishay Semiconductors. It features a 300 V repetitive peak reverse voltage and supports an average forward current of 3 A with a maximum surge current capability of 100 A. The device exhibits a low forward voltage drop of 1.1 V at 3 A and a typical reverse recovery time of 75 ns. Operating within a junction temperature range of -55 °C to +175 °C, it utilizes a hermetically sealed SOD-64 package with plated axial leads.

Feature Summary

• Hermetically sealed glass passivated junction for environmental protection
• Soft recovery characteristics suitable for high-frequency applications
• High pulse current capability with robust avalanche energy rating

Applications

• Fast rectification in switch-mode power supplies (SMPS)
• General-purpose high-speed rectification circuits

Procurement Notes

Verify the specific ordering code suffix against official documentation to confirm packaging format. Confirm that the component meets all required electrical parameters for the target application environment. Ensure compliance with material categorization standards as defined in the manufacturer's documentation before finalizing procurement specifications.

Selection Notes

Select this component when a 300 V blocking voltage and 3 A continuous current are required in a through-hole SOD-64 package. Consider its soft recovery profile and low reverse leakage current for efficient high-speed switching operations. Validate thermal resistance requirements based on the specific lead length and mounting conditions used in the design.

Part Context

This component belongs to the BYW172 series of fast avalanche sinterglass diodes from Vishay Semiconductors. The series includes variants differentiated primarily by their reverse voltage ratings: 200 V (BYW172D), 300 V (BYW172F), and 400 V (BYW172G). All variants share identical physical dimensions and thermal characteristics within the SOD-64 case.

Replacement Considerations

Direct substitutes include the BYW172D and BYW172G models from the same Vishay series, provided the circuit voltage requirements align with their respective 200 V and 400 V ratings.
