GBPC4004

Overview

The GBPC4004 is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features a maximum repetitive peak reverse voltage (Vrrm) of 400 V and an average forward rectified current (If) of 40 A. The device supports a peak non-repetitive forward surge current (Ifsm) of 400 A. Electrical characteristics include a maximum DC blocking current (Ir) of 10 µA and a peak forward voltage drop (Vf) of 1.1 V at rated current. The component operates within a junction temperature range of -55°C to +150°C. It utilizes the GBPC-M package with screw mounting terminals, measuring 29 mm in length, 29 mm in width, and 7.87 mm in height.

Feature Summary

• Glass passivated junctions for reliable operation under high-temperature conditions
• Integrally molded heatsink design providing low thermal resistance for efficient heat dissipation
• Universal four-way terminal configuration supporting snap-on, wrap-around, solder, or PCB mounting methods

Applications

• High current power supply circuits requiring robust rectification
• Industrial equipment utilizing single-phase AC to DC conversion
• General purpose applications demanding high surge overload ratings

Procurement Notes

Verify the specific manufacturer datasheet to confirm exact electrical tolerances and mechanical dimensions before integration. Ensure the selected variant matches the required GBPC-M package style and terminal type. Cross-reference the part number against official Taiwan Semiconductor documentation to validate compliance with specified operating temperatures and surge current capabilities.

Selection Notes

Select this component when a 40 A continuous current rating and 400 V reverse voltage are required in a compact screw-mountable package. Consider the 400 A surge capability for applications with potential inrush currents. Evaluate the thermal management requirements based on the integrally molded heatsink design and the specified maximum junction temperature limit.

Part Context

This component belongs to the GBPC series of high-current single-phase bridge rectifiers. It is designed for general-purpose rectification in environments requiring glass passivation for enhanced reliability. The GBPC4004 shares the standard GBPC footprint with other variants in the series, differing primarily in voltage and current ratings.

Replacement Considerations

Compatible substitutes include the GBPC4004M from the same manufacturer. Other manufacturers produce equivalent parts such as the Luguang GBPC4004. Verify that any replacement maintains the 40 A current rating, 400 V voltage rating, and compatible GBPC package dimensions.
