BYG24J-M3/TR

Overview

The BYG24J-M3/TR is a fast avalanche rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a glass passivated junction and is housed in a low-profile DO-214AC (SMA) surface-mount package. The device supports an average forward current of 1.5 A and offers peak repetitive reverse voltages ranging from 200 V to 600 V, with the 'J' suffix indicating a 200 V rating. Key electrical characteristics include a maximum forward voltage of 1.25 V, a reverse leakage current of 1.0 µA, and a soft recovery time of 140 ns. It operates within a junction temperature range of -55 °C to +150 °C.

Procurement Notes

Verify the specific voltage rating associated with the suffix code against the official datasheet before procurement. Confirm that the DO-214AC package dimensions align with your PCB footprint requirements. Ensure compliance with RoHS and WEEE directives if required by your manufacturing standards. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and traceability.

Selection Notes

Select this component when designing circuits requiring fast recovery times combined with avalanche ruggedness. The 1.5 A current rating suits moderate power applications. Consider the 140 ns reverse recovery time for efficiency in high-frequency converters. The wide operating temperature range allows use in demanding environments. Verify thermal management needs based on the specified junction temperature limits.

Part Context

This component belongs to the BYG series of fast avalanche rectifiers from Vishay. These devices are engineered for high-speed switching applications where standard rectifiers may fail due to energy stress. The series utilizes advanced silicon planar technology to achieve reliable performance in compact surface-mount packages suitable for modern automated assembly lines.

Replacement Considerations

Check for direct substitutes within the same Vishay BYG family with matching voltage ratings. Compare reverse recovery times and forward voltage drops to ensure circuit compatibility. Verify package compatibility for seamless integration into existing designs.
