GBPC2508T

Overview

The GeneSiC Semiconductor GBPC2508T is a single-phase glass-passivated silicon bridge rectifier designed for high-temperature applications. It features an integrally molded heat sink within the GBPC-T package to facilitate efficient thermal dissipation. The device supports a repetitive peak reverse voltage of 800 V and delivers a maximum average forward rectified current of 25 A. Key electrical parameters include a peak forward surge current capability of 300 A, a maximum instantaneous forward voltage drop of 1.1 V per leg, and a typical junction capacitance of 300 pF. The component 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
• Universal 3-way terminals allow snap-on, wire-around, or P.C board mounting
• High temperature soldering guaranteed at 260°C for 10 seconds

Applications

• General purpose rectification in power supplies
• AC to DC conversion circuits
• Industrial equipment requiring high surge current capability

Procurement Notes

Verify the specific manufacturer designation on official documentation, as supply chain records may list alternative brand names for this part number. Confirm the terminal configuration matches the required mounting style, as options include faston lugs or copper leads. Ensure compliance with RoHS standards if applicable to the design requirements before finalizing procurement.

Selection Notes

Select the GBPC2508T when an 800 V reverse voltage rating and 25 A continuous current are required. The GBPC-T package is suitable for bolt-down mounting on heat sinks using silicone thermal compound. Consider the 300 A surge current rating for applications involving capacitive loads, noting that current should be derated by 20% in such scenarios to ensure reliable operation.

Part Context

This component belongs to the GBPC2506T/W through GBPC2510T/W series, which share identical physical dimensions and thermal characteristics. The primary distinction between these variants lies in their voltage ratings, ranging from 600 V to 1000 V. All models in this family utilize the same GBPC-T or GBPC-W package styles and maintain consistent current handling capabilities.

Replacement Considerations

Cross-reference with other manufacturers offering GBPC2508 equivalents. Verify that substitute parts match the 800 V VRRM, 25 A IO, and 1.1 V VF specifications. Ensure the replacement utilizes the same GBPC-T package form factor for mechanical compatibility.
