Overview
The BYT52K-TAP is a fast recovery avalanche rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features an 800 V DC reverse voltage rating and supports a 1.4 A average rectified forward current. The device utilizes SOD-57 axial through-hole packaging. Key electrical characteristics include a maximum forward voltage of 1.3 V at 1 A, a reverse leakage current of 5 µA at 800 V, and a reverse recovery time of 200 ns. It operates within a junction temperature range of -55°C to 175°C.
Feature Summary
- Incorporates avalanche rated technology for enhanced ruggedness and surge capability.
- Provides fast recovery performance with a reverse recovery time of 200 ns.
- Designed for high-temperature operation with a junction temperature range up to 175°C.
Applications
- High-voltage power supply circuits
- Flyback diode applications in switching regulators
- General-purpose rectification in industrial equipment
Procurement Notes
Verify the specific suffix 'TAP' against official datasheets to confirm packaging format, as it may differ from standard tape and reel configurations. Ensure the component meets RoHS3 compliance requirements if applicable to your assembly process. Cross-reference the manufacturer part number directly with Vishay documentation to confirm active status and exact physical dimensions before finalizing procurement.
Selection Notes
Select this component when an 800 V blocking voltage and 1.4 A continuous current are required in an axial package. The avalanche rating makes it suitable for environments with potential voltage transients. Consider the 200 ns reverse recovery time for efficiency in high-frequency switching applications compared to standard recovery diodes.
Part Context
The BYT52K-TAP belongs to the BYT52 series of fast recovery avalanche rectifiers from Vishay. This series is designed for general-purpose rectification where high reliability and surge withstand capability are critical. The 'K' suffix typically denotes the avalanche-rated variant within the family.
Replacement Considerations
BYT52K-TAP is listed as a parametric equivalent to BYT52K-TAP. Verify pinout compatibility and thermal characteristics when substituting with other 800V 1.4A axial fast recovery diodes from different manufacturers.
