GBPC3510T

Overview

The GeneSiC Semiconductor GBPC3510T is a single-phase glass-passivated silicon bridge rectifier designed for high-temperature applications. It features a maximum average forward rectified current of 35 A and a repetitive peak reverse voltage of 1000 V. The device utilizes the GBPC-T package with an integrally molded heat sink, providing a typical junction-to-case thermal resistance of 1.4 °C/W. Electrical characteristics include a maximum instantaneous forward voltage drop of 1.1 V per leg and a maximum DC reverse current of 500 μA at rated blocking voltage. The unit supports a peak forward surge current of 400 A and operates within a temperature range of -55 °C to 150 °C.

Feature Summary

• Universal three-way terminal configuration allowing snap-on, wire-around, or printed circuit board mounting options.
• Integrally molded heat sink structure engineered to provide low thermal resistance for efficient heat dissipation.
• High temperature soldering capability guaranteed at 260°C for 10 seconds under specified tension conditions.

Applications

• General purpose power supply circuits requiring robust rectification.
• Industrial equipment operating in high ambient temperature environments.
• Battery charging systems utilizing resistive or inductive loads.

Procurement Notes

Verify that the specific ordering suffix matches the required terminal type, as the datasheet distinguishes between faston lugs and copper leads. Confirm the thermal interface requirements for the bolt-down mounting position, ensuring silicone thermal compound is available for installation on the heatsink surface. Check mechanical specifications against the target application's torque limits.

Selection Notes

Select this component when a 35 A continuous current rating and 1000 V reverse voltage are required in a compact square package. The GBPC-T package variant is suitable for applications needing specific terminal configurations distinct from the W series. Ensure the design accounts for the 20% current derating if the load is capacitive rather than resistive or inductive.

Part Context

This part belongs to the GBPC3506T/W through GBPC3510T/W family of single-phase bridge rectifiers. The series shares identical mechanical dimensions and thermal characteristics, differing primarily in their voltage ratings. The GBPC3510T represents the highest voltage option in this specific current-rated lineup, offering 1000 V blocking capability while maintaining the same 35 A current handling capacity.

Replacement Considerations

Cross-reference with other manufacturers' GBPC3510 equivalents. Verify that substitute parts maintain the 1.4 °C/W thermal resistance and compatible terminal spacing. Ensure the replacement device supports the same 260°C soldering tolerance and universal mounting terminal types.
