BYG10J-E3/TR3

Overview

The BYG10J-E3/TR3 is a standard avalanche rectifier manufactured by Vishay General Semiconductor. It features a DO-214AC (SMA) surface-mount package with a maximum average forward rectified current of 1.5 A and a repetitive peak reverse voltage of 600 V. The device exhibits a low forward voltage of 1.15 V at rated current and a maximum non-repetitive surge current capability of 30 A. Reverse leakage current is specified at 1 µA, and the component supports a maximum junction temperature of 150 °C.

Feature Summary

• Controlled avalanche characteristics for robust operation in inductive switching environments
• Glass passivated junction providing stable electrical performance and reliability
• Low profile package design optimized for automated surface-mount placement processes

Applications

• General purpose rectification in power supply circuits
• Freewheeling diode applications in converters and inverters
• Consumer electronics power management systems

Procurement Notes

Verify the specific suffix against official documentation to confirm compliance status and qualification level. The E3 suffix indicates RoHS compliance, while HE3 variants may offer different automotive qualifications. Ensure the ordering code matches the required package tape-and-reel configuration for manufacturing integration.

Selection Notes

Select this component when a 600 V rating is required within a compact SMA footprint. The avalanche capability distinguishes it from standard recovery diodes, making it suitable for circuits experiencing voltage transients. Confirm that the 1.5 A continuous current rating aligns with the thermal management strategy of the target application.

Part Context

This part belongs to the BYG series of standard avalanche SMD rectifiers produced by Vishay. The series covers a voltage range from 200 V to 1600 V, all sharing the DO-214AC package form factor. These components are designed to replace bulkier axial leads in modern high-density PCB layouts while maintaining high surge current handling capabilities.

Replacement Considerations

Cross-reference with other Vishay parts in the same voltage class if availability is constrained. Verify that any substitute maintains the avalanche rating and SMA package dimensions to ensure mechanical compatibility.
