BYG24G-M3/TR3

Overview

The BYG24G-M3/TR3 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 and offers reverse voltage ratings ranging from 200 V to 600 V, with the 'G' suffix indicating a 400 V rating. Key electrical characteristics include a maximum reverse leakage current of 1.0 µA, a typical forward voltage of 1.25 V at 1.5 A, and a fast reverse 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 'G' suffix against the official datasheet before procurement. Confirm that the DO-214AC package dimensions match your PCB footprint requirements. Ensure compliance with RoHS directives if required by your manufacturing standards. Check for AEC-Q101 qualification status if automotive application is intended. Validate the reverse recovery time specifications for your specific circuit timing needs.

Selection Notes

Select this component when a fast recovery rectifier with avalanche capability is required in a compact surface-mount format. The 1.5 A current rating suits moderate power applications. Consider the 140 ns reverse recovery time for high-speed switching environments. The wide operating temperature range allows for robust performance in varying thermal conditions. Compare with similar SMA packages if space constraints are critical.
