GBLA01-E3/45

Overview

The GBLA01-E3/45 is a glass-passivated single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features an in-line circuit configuration within the GBL case type, designed for printed circuit board mounting. The device supports a maximum repetitive peak reverse voltage of 100 V and delivers a maximum average forward rectified output current of 4.0 A at a case temperature of 50 °C. Key electrical parameters include a peak forward surge current of 120 A, a maximum instantaneous forward voltage drop of 1.0 V at 4.0 A, and a maximum DC reverse current of 5.0 μA at rated blocking voltage. The component operates within a junction and storage temperature range of -55 to +150 °C.
