Overview
The BYV28-100-TR is an ultra-fast avalanche sinterglass diode manufactured by Vishay General Semiconductor - Diodes Division. It features a single rectifier configuration in an SOD-64 axial package with glass passivated junctions. The device supports an average forward current of 3.5 A and a repetitive peak reverse voltage of 100 V. Key electrical parameters include a maximum forward voltage of 1.1 V at 5 A, a reverse recovery time of 30 ns, and a non-repetitive peak surge current of 90 A. It operates within a junction temperature range of -55 °C to +175 °C.
Feature Summary
- Controlled avalanche characteristic for energy dissipation
- Ultra-fast recovery time for high-speed switching
- Hermetically sealed glass passivated junction
- AEC-Q101 qualified for automotive reliability
Applications
- Very fast rectification in switch mode power supplies
Procurement Notes
Verify the specific ordering code matches the required tape and reel quantity of 12,500 units per 10-inch tape. Confirm that the component meets AEC-Q101 qualification requirements if intended for automotive applications. Ensure the SOD-64 package dimensions align with the target PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when designing circuits requiring controlled avalanche capability alongside ultra-fast recovery characteristics. The SOD-64 package provides a compact solution for through-hole mounting. Consider the thermal resistance values relative to the expected ambient temperature and lead length to ensure safe operation within the specified junction temperature limits.
Part Context
This part belongs to the BYV28 series of ultra-fast avalanche sinterglass diodes from Vishay Semiconductors. The series includes variants differentiated by their reverse voltage ratings: 50 V, 100 V, 150 V, and 200 V. All variants share the same 3.5 A average forward current rating and SOD-64 package type, offering consistent performance characteristics across different voltage levels.
