GBPC4008

Overview

The GBPC4008 is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features a maximum average forward rectified current of 40A and a repetitive peak reverse voltage rating of 800V. The device utilizes glass passivated junctions for enhanced reliability and includes an integrally molded heatsink to ensure low thermal resistance. Electrical characteristics include a typical reverse leakage current of less than 0.2 uA and surge overload ratings up to 400 amperes. The component supports high-temperature soldering at 260°C for ten seconds and provides isolated voltage from the case to leads exceeding 2500 volts.

Feature Summary

• Glass passivated junctions provide robust protection against voltage transients.
• Integrally molded heatsink design facilitates efficient heat dissipation.
• Universal four-way terminal configuration allows snap-on, wrap-around, or PCB mounting.

Applications

• High current power supply circuits
• Battery charging systems
• Industrial motor control drives
