GBPC5004T

Overview

The GeneSiC Semiconductor GBPC5004T is a single-phase silicon bridge rectifier designed for high-power applications. It features a maximum average forward rectified current (IO) of 50 A and a repetitive peak reverse voltage (VRRM) of 400 V. The device supports a peak forward surge current (IFSM) of 400 A and operates within a junction temperature range of -55 °C to +150 °C. Electrical characteristics include a maximum instantaneous forward voltage drop of 1.2 V per leg and a typical thermal resistance (RΘJC) of 1.2 °C/W. The component utilizes the GBPC-T package with screw mounting terminals.

Feature Summary

• Integrally molded heat sink provides low thermal resistance for maximum heat dissipation
• Universal 3-way terminals allow snap-on, wire-around, or P.C board mounting
• High surge current capability ensures robust performance under transient loads

Applications

• General purpose power supply circuits
• Industrial motor control systems
• Battery charging equipment

Procurement Notes

Verify the specific suffix 'T' corresponds to the GBPC-T package variant with faston lugs or copper leads as defined in the official datasheet. Confirm that the manufacturer designation aligns with GeneSiC Semiconductor specifications. Ensure compliance with RoHS directives if required by the target application environment before finalizing procurement orders.

Selection Notes

Select this component when a 50 A continuous current rating and 400 V blocking voltage are required. The GBPC-T package is suitable for bolt-down mounting on heat sinks using silicone thermal compound. Consider the 1.2 °C/W thermal resistance for heatsink sizing calculations. Derate current by 20% if used with capacitive loads to ensure reliable operation within specified temperature limits.

Part Context

The GBPC5004T belongs to the GBPC50005T/W through GBPC5004T/W series of single-phase glass passivated silicon bridge rectifiers. This family shares common mechanical dimensions and thermal characteristics, differing primarily in their voltage ratings. The GBPC5004T specifically addresses applications requiring 400 V reverse voltage capability while maintaining the standard 50 A current handling capacity of the series.

Replacement Considerations

Cross-reference with other manufacturers offering GBPC package bridge rectifiers rated at 50 A and 400 V. Verify terminal configuration compatibility, as the GBPC-T variant uses specific faston lugs or copper leads distinct from other package styles.
