Overview
The BYW74TAP is a silicon rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a single-phase, one-element configuration housed in an SOD-64 through-hole package. The device supports a maximum repetitive reverse voltage of 400 V and an average forward rectified current of 3 A. It withstands a non-repetitive peak forward surge current of 100 A. Operating temperatures range from -65 °C to 175 °C junction temperature.
Feature Summary
- Glass passivated junction for enhanced reliability
- Hermetically sealed plastic package construction
- Soft recovery characteristics suitable for high-frequency applications
- Low reverse leakage current performance
Applications
- General purpose rectification
- Free wheeling diode circuits
- High frequency switching applications
Procurement Notes
Verify the specific suffix 'TAP' against official Vishay documentation to confirm tape-and-reel packaging and exact electrical tolerances. Ensure the component matches the SOD-64 form factor required for your PCB layout. Cross-reference datasheet revisions to confirm material categorization and compliance status prior to finalizing procurement orders.
Selection Notes
Select this component when a 400 V blocking capability and 3 A continuous current rating are required in a compact axial leaded format. Consider the soft recovery feature if minimizing switching losses or electromagnetic interference is critical. Verify thermal management requirements given the 175 °C maximum junction temperature limit for high-power density designs.
Part Context
This part belongs to Vishay's general-purpose rectifier diode family. It utilizes glass passivation technology to protect the silicon junction. The SOD-64 package provides a robust mechanical solution for through-hole mounting. It is distinct from surface-mount variants within the same voltage and current class.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult official Vishay cross-reference tools for verified equivalents.
