Overview
The BYT51G-TR is a single avalanche rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current of 1.5 A. The device is housed in a SOD-57 through-hole package, also identified as SOD-57. It supports a surge forward current (IFSM) of 50 A. The component utilizes glass passivation for the junction and is designed for general-purpose rectification applications requiring avalanche ruggedness.
Feature Summary
- Glass passivated junction for enhanced reliability
- Hermetically sealed package construction
- Low reverse leakage current characteristics
- Avalanche rated for robust operation
Applications
- General purpose rectification in power supplies
- Automation equipment circuits
- Low-noise signal processing interfaces
Procurement Notes
Verify the specific suffix TR indicates tape and reel packaging configuration when sourcing. Confirm RoHS compliance status and lead-free material composition against the latest manufacturer datasheet revision. Ensure the SOD-57 footprint matches the target PCB design requirements before finalizing procurement orders.
Selection Notes
Select this component for applications requiring 400 V blocking capability with 1.5 A continuous current handling. The SOD-57 through-hole package suits designs preferring axial or radial leaded mounting over surface mount alternatives. Consider the 50 A surge rating for transient protection scenarios within the circuit design parameters.
Part Context
This part belongs to the Vishay BYT series of fast recovery and avalanche rectifier diodes. The series offers various voltage ratings including 600 V variants like the BYT51J-TR. The BYT51G-TR specifically targets the 400 V class, providing a balance of speed and ruggedness for industrial and consumer electronics applications.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with equivalent 400 V 1.5 A SOD-57 avalanche diodes from other manufacturers based on electrical specifications and mechanical dimensions.
