Overview
The BYT51D-TR is a fast recovery rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features an 800 V DC reverse voltage rating and supports a continuous forward current of 1.5 A. The device utilizes avalanche technology and is housed in a SOD-57 axial through-hole package. Its maximum reverse leakage current is specified at 5 µA when tested at the rated voltage. The component operates within a junction temperature range of -55°C to +175°C, ensuring reliability under varying thermal conditions.
Feature Summary
- Fast recovery rectification capability for efficient switching applications
- Avalanche ruggedness for enhanced transient protection
- High-temperature operation up to 175°C junction temperature
Applications
- High-frequency power supply circuits
- Free-wheeling diode applications in inductive loads
- General-purpose rectification in industrial equipment
Procurement Notes
Verify the specific suffix TR indicates tape-and-reel packaging configuration. Confirm the manufacturer part number matches the exact electrical specifications required for the design. Check for RoHS compliance status as per current datasheet revisions. Ensure the ordering quantity aligns with standard reel sizes provided by the distributor.
Selection Notes
Select this component where high-voltage blocking and fast switching are required in a compact axial package. Compare the 800V rating against peak inverse voltage requirements in the circuit. Evaluate the 1.5A current capacity against load profiles. Consider the SOD-57 footprint constraints during PCB layout planning.
Part Context
This part belongs to the BYT series of fast recovery rectifiers from Vishay. These components are designed for general-purpose use in demanding environments. The series offers various voltage ratings and current capabilities to suit different power electronics needs. The BYT51D variant specifically targets higher voltage applications within the family.
Replacement Considerations
Check for direct cross-reference parts with identical 800V/1.5A ratings and SOD-57 packages. Verify pinout compatibility and thermal characteristics before substitution. Ensure any alternative meets the same fast recovery time and avalanche energy specifications.
