GBU404 Description

Short technical summary and product information.

The GBU404 from Comchip Technology is a glass passivated bridge rectifier designed for use in various electronic applications. It offers a maximum average forward rectified current of 4.0A with a heatsink at 100°C, and a peak repetitive reverse voltage of up to 1000V.

This bridge rectifier has a high surge overload rating of 150 amperes peak for an 8.3ms single half sine-wave, making it robust for demanding conditions. The maximum forward voltage is 1.1V at 4.0A DC. It operates within a temperature range of -55°C to +150°C.

Designed for printed circuit board (PCB) mounting, the GBU404 comes in a molded plastic GBU case. Its epoxy meets UL 94V-0 rate flame retardant standards. The typical thermal resistance is 2.2°C/W when mounted on a heatsink.

Key electrical characteristics include a maximum DC blocking voltage of 1000V and a typical junction capacitance of 20pF per element. The device is suitable for single-phase, half-wave applications with resistive or inductive loads.
