GBPC1508T

Overview

The GeneSiC Semiconductor GBPC1508T is a single-phase glass-passivated silicon bridge rectifier designed for high-reliability power conversion applications. It features an integrally molded heat sink within the encapsulation to ensure low thermal resistance and efficient heat dissipation. The component supports a maximum average forward rectified current of 15.0 A and withstands a repetitive peak reverse voltage of 800 V. Electrical characteristics include a maximum instantaneous forward voltage drop of 1.1 V per leg and a peak forward surge current capability of 300 A. The device operates reliably across a temperature range from -55 °C to +150 °C.

Feature Summary

• Integrally molded heat sink provides low thermal resistance for maximum heat dissipation
• Glass passivated chip junctions ensure high reliability and stability
• Universal three-way terminals allow snap-on, wire-around, or PCB mounting options
• High temperature soldering guaranteed at 260°C for 10 seconds

Applications

• General purpose AC to DC power supply circuits
• Battery charging systems requiring robust surge handling
• Industrial equipment with high thermal load requirements

Procurement Notes

Verify the specific terminal configuration before ordering, as the datasheet distinguishes between the GBPC-T package (Faston lugs) and GBPC-W package (copper leads). Confirm that the manufacturer designation aligns with current production sources, as branding may vary while specifications remain consistent. Ensure compliance with RoHS directives if required by the application environment.

Selection Notes

Select this component when an 800 V blocking voltage is necessary for single-phase rectification. The 15 A continuous current rating suits moderate power applications. Consider the 1.9 °C/W thermal resistance for heatsink design calculations. Verify that the operating ambient temperature does not exceed limits without appropriate derating, particularly for capacitive loads which require a 20% current reduction.

Part Context

This part belongs to the GBPC series of single-phase bridge rectifiers, which are widely used in industrial and consumer electronics. The series offers various voltage ratings from 50 V to 1000 V with current capacities ranging from 12 A to 35 A. The GBPC1508T specifically addresses the 800 V requirement within the 15 A current class, providing a standard solution for medium-voltage AC rectification tasks.

Replacement Considerations

Compatible substitutes include the GBPC1508W variant, which shares identical electrical parameters but utilizes copper leads instead of Faston lugs. Other manufacturers producing equivalent 15 A, 800 V bridge rectifiers in the GBPC form factor may also serve as functional replacements provided mechanical dimensions and terminal types match.
