Overview
The BYT53B-TAP is a single ultra-fast recovery rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a 100 V maximum repetitive peak reverse voltage and supports an average forward current of 1.9 A. The device exhibits a fast reverse recovery time of 50 ns and a low forward voltage drop of 1.1 V at rated current. It is designed for through-hole mounting in the SOD-57 axial package. The component withstands a maximum surge current of 50 A and operates within a junction temperature range of -55 °C to +175 °C.
Feature Summary
- Ultra-fast recovery characteristics with 50 ns reverse recovery time
- High thermal stability supporting operation up to +175 °C
- Robust surge current handling capability of 50 A
Applications
- High-frequency switching power supplies
- Free-wheeling diode applications in DC-DC converters
- General purpose rectification in electronic circuits
Procurement Notes
Verify the specific ordering suffix TAP against the manufacturer's official datasheet to confirm packaging details, as suffixes often denote tape-and-reel quantities or specific reel configurations. Ensure the selected variant matches the required axial lead form factor and that the component status is active for production use.
Selection Notes
Select this component when a fast recovery diode with low forward voltage is required in an axial package. The 100 V rating suits low-voltage AC/DC conversion stages. Compare the 1.9 A continuous current limit against circuit load requirements to ensure adequate derating margins under high ambient temperatures.
Part Context
This part belongs to the BYT series of ultra-fast recovery rectifiers from Vishay. These components are engineered for efficiency in high-speed switching environments. The SOD-57 package provides a compact solution for through-hole PCB assembly while maintaining reliable electrical performance across wide temperature ranges.
Replacement Considerations
Consult official cross-reference lists for direct substitutes. Verify that any alternative maintains the same 50 ns recovery time, 1.9 A current rating, and SOD-57 package dimensions to ensure mechanical and electrical compatibility.
