BYM12-200HE3/97

Overview

The BYM12-200HE3/97 is a surface-mount ultrafast rectifier manufactured by Vishay General Semiconductor. It utilizes a Superectifier structure with a cavity-free glass-passivated junction in the GL41 (DO-213AB) package. The device supports a maximum average forward rectified current of 1.0 A and offers a peak reverse repetitive voltage rating of 200 V. Key electrical characteristics include a maximum instantaneous forward voltage of 1.25 V at 1.0 A, a peak non-repetitive forward surge current of 30 A, and an ultrafast maximum reverse recovery time of 50 ns. The component operates within a junction temperature range of -65 °C to +175 °C.
