Overview
The BY448TR is a standard avalanche sinterglass diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 1500 V and an average forward rectified current of 2 A. The device supports a maximum surge forward current of 30 A. Key electrical parameters include a maximum forward voltage of 1.6 V at 2 A, a maximum reverse leakage current of 3 µA, and a typical reverse recovery time of 20 µs. It operates within a junction temperature range of -55 °C to +140 °C.
Feature Summary
- Incorporates avalanche ruggedness for enhanced reliability under transient conditions
- Utilizes sinterglass passivation technology for stable high-voltage performance
- Designed for through-hole mounting in the SOD-57 package
Applications
- High-voltage rectification circuits
- Horizontal deflection systems in display equipment
- General-purpose power supply designs requiring robust avalanche capability
Procurement Notes
Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm RoHS compliance status with the manufacturer as requirements may vary by production batch. Ensure the procurement documentation explicitly references the Vishay General Semiconductor part number BY448TR to avoid confusion with similar standard recovery diodes lacking avalanche ratings.
Selection Notes
Select this component when circuit design requires a 1500 V rating combined with 2 A continuous current handling. The avalanche characteristic makes it suitable for applications prone to voltage spikes or inductive load switching. Compare against non-avalanche variants if transient immunity is not required, noting that the SOD-57 package dictates specific PCB footprint constraints for through-hole assembly.
Part Context
This component belongs to the BY448GP series of standard recovery rectifiers from Vishay. It is distinct from fast-recovery or Schottky diodes due to its 20 µs reverse recovery time. The SOD-57 package provides a compact form factor compared to larger axial leads, while maintaining the thermal and electrical characteristics necessary for industrial-grade power electronics applications.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Verify pinout compatibility and thermal resistance values before considering any alternative manufacturers' components.
