BYG24J-E3/TR

Overview

The BYG24J-E3/TR is a fast avalanche rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a glass passivated junction and is housed in the DO-214AC (SMA) surface-mount package. The device supports an average forward current of 1.5 A with peak repetitive reverse voltages ranging from 200 V to 600 V. Key electrical characteristics include a maximum reverse leakage current of 1.0 µA, a typical forward voltage of 1.25 V, and a fast reverse recovery time of 140 ns. It operates within a junction temperature range up to 150 °C.

Feature Summary

• Fast avalanche technology designed for high-frequency rectification
• Glass passivated junction ensures low reverse current and soft recovery characteristics
• Low profile package suitable for automated placement processes

Applications

• High frequency rectification in switching mode converters
• Freewheeling applications in inverters
• Consumer electronics power supplies
• Computer equipment power circuits
• Automotive electronic systems
• Telecommunication infrastructure

Procurement Notes

Verify the specific voltage sub-rating required for your design, as the base part number covers a range from 200 V to 600 V. Confirm that the DO-214AC (SMA) package dimensions align with your PCB footprint. Ensure compliance with RoHS Directive 2002/95/EC and WEEE 2002/96/EC standards if applicable to your manufacturing region. Check for AEC-Q101 qualification requirements if the component is intended for automotive use.

Selection Notes

Select this component when fast recovery and avalanche ruggedness are required in a compact surface-mount form factor. The 1.5 A current rating makes it suitable for moderate power applications where space is constrained. Consider the 140 ns reverse recovery time for efficiency in high-frequency switching environments. Verify thermal management capabilities given the 150 °C maximum junction temperature limit.

Part Context

This component belongs to Vishay's Fast Avalanche SMD Rectifier series, which utilizes advanced semiconductor technology to enhance performance in demanding power conversion applications. The series is engineered to meet the needs of modern electronics requiring reliable operation in consumer, computer, automotive, and telecommunication sectors. The E3 suffix indicates compliance with environmental directives.

Replacement Considerations

Direct substitutes must match the 1.5 A current rating, DO-214AC package, and similar reverse recovery specifications. Verify voltage ratings against the specific application requirement within the 200 V to 600 V range. Ensure any replacement also offers glass passivation and avalanche capability if those features are critical to the circuit design.
