GBPC2506

Overview

The onsemi GBPC2506 is a single-phase bridge rectifier from the GBPC25 series, rated for an average forward current of 25 A at a case temperature of 55°C. It features a maximum repetitive reverse voltage of 600 V and a non-repetitive peak forward surge current capability of 300 A. The device utilizes a molded plastic package with an integrally mounted metal heat sink to ensure low thermal resistance. Electrical characteristics include a maximum forward voltage drop of 1.1 V at 12.5 A and a maximum reverse leakage current of 5 µA at 25°C. The component operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Integrally molded heat sink provides very low thermal resistance for maximum heat dissipation.
• Surge overload ratings support up to 300 A for non-repetitive peak forward currents.
• Provides isolated voltage from case to lead exceeding 2500 V.

Applications

• Power supply circuits requiring high current rectification.
• Industrial equipment utilizing resistive or inductive loads.
• General purpose applications compatible with half-wave configurations.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm terminal finish and mounting style. The standard GBPC package utilizes nickel terminals suitable for screw mounting, whereas the W suffix indicates wire leads with silver plating. Confirm compliance requirements such as UL certification number E258596 and RoHS status prior to procurement.

Selection Notes

Select this component based on the required voltage rating of 600 V and the continuous current demand of 25 A. Ensure the application allows for adequate heatsinking to maintain the case temperature at or below 55°C for full current rating. Verify that the mechanical mounting torque does not exceed 20 in-lbs to prevent damage to the package structure.

Part Context

This part belongs to the GBPC 12, 15, 25, and 35 series of bridge rectifiers manufactured by onsemi. The series offers various voltage ratings ranging from 50 V to 1000 V while maintaining consistent physical dimensions and thermal characteristics across the different current variants.

Replacement Considerations

Direct substitutes within the same series include the GBPC2504 (400 V) and GBPC2508 (800 V). Cross-manufacturer equivalents must match the 25 A current rating, 600 V blocking voltage, and GBPC package footprint.
