Overview
The BYT51B-TR is a fast recovery avalanche rectifier diode manufactured by Vishay General Semiconductor. It features a 100V DC reverse voltage rating and supports a continuous forward current of 1.5A. The device utilizes SOD-57 through-hole packaging. Key electrical parameters include a maximum reverse recovery time of 4µs, a peak forward surge current capability of 50A, and a typical forward voltage drop of 1.1V at 1A. These specifications define its operational limits within electronic circuits.
Feature Summary
- Fast recovery avalanche technology for efficient switching
- Sinter glass construction for robust performance
- Unidirectional conduction with high blocking capability
Applications
- High-frequency rectification in power supplies
- Free-wheeling diodes in inductive load circuits
- Snubber circuits for voltage spike suppression
Procurement Notes
Verify the specific suffix 'TR' indicates tape and reel packaging when sourcing. Confirm the manufacturer designation as Vishay General Semiconductor - Diodes Division to ensure component authenticity. Cross-reference the SOD-57 package dimensions against your PCB footprint requirements prior to assembly. Ensure storage conditions align with semiconductor handling standards.
Selection Notes
Select this component where fast recovery characteristics are required alongside avalanche ruggedness. The 100V rating suits low-voltage DC applications. Consider the 1.5A current limit for load matching. The SOD-57 package dictates through-hole mounting constraints. Evaluate thermal management needs based on the 1.1V forward voltage drop at operating currents.
Part Context
This part belongs to the BYT51 series of fast recovery avalanche rectifiers from Vishay. The series offers various voltage ratings including 200V, 400V, and 600V options. The BYT51B variant specifically targets 100V applications. The TR suffix denotes bulk tape packaging for automated insertion processes.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with generic equivalents only if they match the 100V, 1.5A, 4µs trr, and SOD-57 specifications exactly.
