Overview
The BYT51K-TAP is a fast recovery rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It utilizes FRED Pt technology to achieve low reverse recovery charge and short switching times, making it suitable for high-frequency applications. The device is housed in a DO-201AD (DO-15) axial-leaded package designed for through-hole mounting. Key electrical characteristics include a maximum repetitive peak reverse voltage of 50 V and an average forward rectified current rating of 3 A. The component operates within a junction temperature range of -65°C to +175°C.
Feature Summary
- Incorporates FRED Pt technology for optimized reverse recovery performance
- Features low internal power dissipation and high efficiency
- Engineered for high reliability and long-term stability
Applications
- High-frequency rectification circuits
- Free-wheeling diodes in DC-DC converters
- Snubber circuits in power supplies
Procurement Notes
Verify the specific suffix 'K' against the official datasheet to confirm exact mechanical dimensions and marking codes. Ensure the ordering code matches the required tape-and-reel quantity if applicable. Cross-reference the manufacturer part number with the distributor's listing to confirm the package type and lead finish specifications before finalizing procurement.
Selection Notes
Select this component when a 3 A current rating and 50 V blocking voltage are required in an axial package. Consider the FRED Pt technology benefits for reducing switching losses in high-frequency environments. Evaluate thermal management requirements based on the specified junction temperature range and ensure the PCB layout supports the through-hole mounting style effectively.
Part Context
This component belongs to Vishay's BYT series of fast recovery rectifiers. The series is characterized by the use of Platinum-doped Fast Recovery Epitaxial Diode (FRED Pt) technology. This technology family is designed to provide superior switching performance compared to standard recovery diodes, addressing the needs of modern high-efficiency power conversion systems.
Replacement Considerations
Consult official substitution guides for equivalent FRED Pt devices from Vishay or other manufacturers offering similar 3 A, 50 V axial packages. Verify that any substitute maintains compatible reverse recovery time and forward voltage characteristics.
