BYWB29-50-E3/81

Overview

The BYWB29-50-E3/81 is an ultrafast rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a glass passivated pellet chip junction and operates in a single circuit configuration within a D2PAK (TO-263AB) package. Key electrical parameters include a maximum repetitive peak reverse voltage of 50 V, a maximum average forward rectified current of 8.0 A at 105 °C case temperature, and a peak forward surge current of 100 A. The device exhibits a maximum instantaneous forward voltage of 1.3 V at 20 A and 25 °C, with a typical junction capacitance of 45 pF. Maximum operating and storage temperatures range from -65 to +150 °C.
