GBPC3506T

Overview

The GeneSiC Semiconductor GBPC3506T is a single-phase glass-passivated silicon bridge rectifier designed for high-temperature applications. It features a maximum average forward rectified current of 35.0 A and a repetitive peak reverse voltage of 600 V. The device supports a peak forward surge current of 400 A and operates within a junction temperature range of -55 to 150 °C. Key electrical parameters include a maximum instantaneous forward voltage drop of 1.1 V per leg, a typical thermal resistance of 1.4 °C/W, and an RMS isolation voltage of 2500 V from case to leads.

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 temperature soldering guaranteed at 260°C/10 seconds under tension

Applications

• Power supply circuits requiring high surge current capability
• General purpose rectification in industrial equipment
• Applications utilizing bolt-down mounting on heat-sinks with silicone thermal compound

Procurement Notes

Verify the specific terminal configuration upon ordering, as the datasheet indicates availability with either nickel-plated 0.25-inch Faston lugs or copper leads with a 0.040-inch diameter. Confirm that the component meets the required mechanical mounting torque specifications of 20 inch-lbs max for secure installation on heat sinks.

Selection Notes

Select this component when a 35 A continuous current rating and 600 V blocking voltage are required in a compact form factor. Ensure the application environment stays within the specified -55 to 150 °C operating temperature range. Consider the 1.4 °C/W thermal resistance for heat sink sizing calculations to maintain safe junction temperatures under load.

Part Context

This part belongs to the GBPC-T/W series, which includes variants such as the GBPC3508T/W and GBPC3510T/W. These components share similar physical dimensions and thermal characteristics but differ primarily in their repetitive peak reverse voltage ratings, ranging from 600 V to 1000 V across the series.

Replacement Considerations

Cross-reference with other manufacturers' GBPC3506 equivalents. Verify that substitute parts match the 35 A current rating, 600 V reverse voltage, and compatible terminal types (Faston lugs vs. copper leads) to ensure mechanical fit.
