Overview
The BYT52B-TR is a fast recovery avalanche rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a 100V repetitive peak reverse voltage and a 1.4A average forward current rating. The device utilizes a SOD-57 surface-mount package. Key electrical parameters include a maximum forward voltage of 1.3V at 1A, a reverse recovery time of 200ns, and an avalanche energy capability. It is designed for general-purpose rectification applications requiring fast switching characteristics.
Feature Summary
- Fast recovery performance with 200ns reverse recovery time
- Avalanche rated for robust operation in inductive load switching
- Surface-mount SOD-57 package for automated assembly
Applications
- General purpose rectification in power supplies
- Inductive load switching circuits
- Free-wheeling diode applications
Procurement Notes
Verify the specific suffix against official Vishay documentation to confirm exact electrical tolerances and packaging variations. Ensure the component matches the required SOD-57 footprint and pin configuration for your PCB layout. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement specifications.
Selection Notes
Select this component when a fast-recovery rectifier with avalanche capability is required in a compact surface-mount form factor. The 1.4A current rating and 100V blocking voltage suit low-voltage, high-frequency switching environments. Evaluate thermal management requirements based on the SOD-57 package's power dissipation limits under continuous operating conditions.
Part Context
This part belongs to Vishay's BYT series of fast recovery rectifiers. The series offers various voltage ratings and packages. The BYT52B-TR specifically targets applications needing rapid switching speeds and avalanche ruggedness in a small outline package, distinguishing it from standard recovery diodes or through-hole variants within the broader product family.
Replacement Considerations
Consult official substitution guides for equivalent fast recovery rectifiers with matching 1.4A current and 100V voltage ratings. Verify that any substitute maintains the SOD-57 package dimensions and avalanche energy specifications to ensure circuit compatibility without redesign.
