GBPC2502W

Overview

The onsemi GBPC2502W is a single-phase bridge rectifier from the GBPC25 series, featuring a wire lead structure (suffix W) and an average forward current rating of 25 A at a case temperature of 55°C. It has a maximum repetitive reverse voltage of 200 V and a non-repetitive peak forward surge current capability of 300 A for an 8.3 ms half-sine wave. The device operates within a junction temperature range of -55°C to +150°C, with a maximum forward voltage drop of 1.1 V at 12.5 A and a reverse leakage current of 5 µA at 25°C. It utilizes a GBPC-W package with silver-plated terminals.

Feature Summary

• Integrally molded heat sink provides very low thermal resistance for maximum heat dissipation.
• Surge overload ratings support high transient currents up to 300 A.
• Provides isolated voltage from the case to the leads exceeding 2500 V.
• Terminals are finished with silver, ensuring solderability per MIL-STD-208.

Applications

• General-purpose AC to DC power supply conversion.
• Battery charging circuits requiring robust surge handling.
• Industrial equipment power stages operating under moderate thermal loads.

Procurement Notes

Verify the specific suffix 'W' indicates the wire lead configuration rather than standard screw mount variants. Confirm that the component is marked as Pb-Free and complies with RoHS directives. Check the manufacturer's discontinuation status, as certain older revisions may be phased out. Ensure the ordering quantity aligns with bulk packing methods specified in the official documentation.

Selection Notes

Select this component when a 200 V blocking voltage and 25 A continuous current are required in a through-hole wire lead format. Compare the 1.5 °C/W junction-to-case thermal resistance against your heatsinking strategy. Ensure the application does not exceed the 300 A surge limit during startup or fault conditions. Verify that the 2500 V isolation rating meets safety requirements between the circuit and the enclosure.

Part Context

This part belongs to the GBPC 12, 15, 25, and 35 series of glass-passivated bridge rectifiers. The 'GBPC25' designation specifically denotes the 25 A current class within this family. The 'W' suffix differentiates it from the standard GBPC package by providing a wire lead structure instead of screw terminals, facilitating different PCB mounting techniques.

Replacement Considerations

Direct replacements must match the 25 A current rating, 200 V reverse voltage, and GBPC-W package dimensions. Verify that substitute components maintain the same 1.1 V forward voltage drop and 300 A surge capability. Ensure the replacement also offers comparable thermal resistance and terminal finish specifications.
