Overview
The BYX82TR is a surface-mount avalanche rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a 200 V reverse voltage rating and a continuous forward current of 2 A. The device utilizes the SOD-57 package, which offers high thermal stability and reliability. Key electrical parameters include a maximum forward voltage of 1 V at 1 A and a peak surge current capability of 50 A. The component is designed for applications requiring robust transient protection and efficient power conversion in compact form factors.
Feature Summary
- Avalanche rated construction for enhanced ruggedness
- High thermal stability suitable for demanding environments
- Compact SOD-57 surface mount package design
Applications
- General purpose rectification in power supplies
- Transient voltage suppression circuits
- Automotive electronics modules
Procurement Notes
Verify the specific suffix 'TR' indicates tape and reel packaging when sourcing. Confirm the manufacturer designation matches Vishay General Semiconductor - Diodes Division to ensure authenticity. Check for RoHS compliance documentation if required by your manufacturing standards. Ensure the part status is active before finalizing procurement plans.
Selection Notes
Select this component when a 200 V blocking voltage and 2 A continuous current are required in a small outline package. The avalanche rating makes it suitable for inductive load switching where standard rectifiers might fail. Compare the SOD-57 footprint against available board space constraints. Consider the 1 V forward voltage drop for efficiency calculations in low-voltage output stages.
Part Context
This device belongs to the BYX series of avalanche rectifiers from Vishay. These components are engineered to withstand repetitive avalanche conditions, offering higher reliability than standard rectifiers in harsh electrical environments. The series supports various voltage ratings while maintaining consistent current handling capabilities across the lineup.
Replacement Considerations
The BYW32-TR is identified as an alternative part with similar specifications. Verify pinout compatibility and exact voltage/current ratings before substitution. Ensure the replacement meets the same automotive or industrial qualification standards if applicable.
