Overview
The BYX83TR is a standard avalanche sinterglass diode manufactured by Vishay General Semiconductor - Diodes Division. It features a 400 V repetitive peak reverse voltage and a 2 A average forward rectifying current capability. The device supports a 50 A non-repetitive peak forward surge current (IFSM). It is housed in the SOD-57 through-hole package, designed for robust performance in general-purpose rectification applications requiring avalanche ruggedness.
Feature Summary
- Utilizes sinterglass construction for enhanced thermal stability and reliability under high-stress conditions.
- Engineered with avalanche characteristics to withstand transient energy events without failure.
- Provides reliable rectification in through-hole mounting configurations.
Applications
- General-purpose rectification circuits
- Power supply input stages
- Protection against voltage transients
Procurement Notes
Verify the specific suffix 'TR' indicates the tape-and-reel packaging format when sourcing. Confirm the manufacturer is Vishay General Semiconductor - Diodes Division to ensure component authenticity. Cross-reference the datasheet for absolute maximum ratings before integration into designs.
Selection Notes
Select this component for applications requiring 400 V blocking capability and 2 A continuous current handling. The SOD-57 package suits through-hole assembly processes. Ensure the circuit design accounts for the 50 A surge current rating during startup or fault conditions.
Part Context
This part belongs to the BYX83 series of standard avalanche diodes from Vishay. These components are distinguished by their sinterglass technology, which offers superior mechanical strength compared to conventional glass-passivated diodes. The series is widely used in industrial and consumer electronics where reliability is critical.
Replacement Considerations
Check for compatible parts within the same Vishay series, such as BYX83TAP, ensuring identical electrical ratings and package dimensions. Verify that any substitute maintains the avalanche characteristic and sinterglass construction for equivalent performance.
