GBPC1510T

Overview

The GeneSiC Semiconductor GBPC1510T is a single-phase glass-passivated silicon bridge rectifier designed for high-temperature applications. It features an average forward rectified current of 15 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 thermal resistance of 1.9 °C/W. Key electrical parameters include a maximum instantaneous forward voltage drop of 1.1 V per leg and a peak forward surge current capability of 300 A. The unit supports an operating temperature range from -55 °C to 150 °C and includes universal 3-way terminals for flexible mounting.

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 for 10 seconds
• Void-free junction soldering achieved through vacuum soldering process

Applications

• Single phase half wave rectification in resistive or inductive loads
• Bolt down mounting on heat-sinks using silicone thermal compound
• General purpose power supply circuits requiring high surge current capability

Procurement Notes

Verify the specific terminal configuration required, as the GBPC-T variant uses nickel-plated faston lugs or copper leads rather than standard PCB pins. Confirm that the application environment remains within the specified -55 °C to 150 °C operating temperature range. Ensure proper torque is applied during bolt-down installation to maintain thermal performance and mechanical integrity without damaging the plastic encapsulation.

Selection Notes

Select this component when a 15 A continuous current rating and 1000 V reverse voltage are required in a compact bridge rectifier form factor. The GBPC-T package is suitable for applications needing direct heat-sink mounting with integrated thermal management. Consider the 1.1 V forward voltage drop for efficiency calculations and verify that the 300 A surge current rating meets the circuit's transient requirements.

Part Context

This part belongs to the GBPC1506T/W through GBPC1510T/W series, which shares identical electrical characteristics except for the reverse voltage rating. The 'T' suffix denotes the use of the GBPC-T package with specific terminal types. This series is designed as a glass-passivated silicon bridge rectifier, offering reliability in high-temperature environments compared to non-passivated alternatives.

Replacement Considerations

Direct replacements must match the 15 A current rating, 1000 V reverse voltage, and GBPC-T package dimensions. Verify terminal compatibility, as the T-package uses distinct faston lugs or copper leads compared to the W-package's wire structure. Ensure the substitute component also offers glass passivation and similar thermal resistance characteristics.
