GBPC15005W

Overview

The onsemi GBPC15005W is a single-phase bridge rectifier from the GBPC series, rated for an average forward current of 15 A at a case temperature of 55°C. It features a maximum repetitive peak reverse voltage of 50 V and a non-repetitive peak forward surge current of 300 A (8.3 ms half-sine-wave). The device utilizes glass passivation for junction protection and offers a low thermal resistance of 1.5°C/W junction-to-case with a heatsink. Electrical characteristics include a maximum forward voltage drop of 1.1 V at 7.5 A and a maximum reverse 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
• Glass passivated chip junctions ensure high reliability and stability
• Wire lead structure facilitates through-hole mounting applications
• UL certified under file number E258596

Applications

• Power supply units requiring AC to DC conversion
• Battery charging circuits
• General-purpose rectification in industrial equipment

Procurement Notes

Verify the specific ordering suffix 'W' corresponds to the wire lead package variant when sourcing. Confirm RoHS compliance status as the datasheet indicates these are Pb-Free devices. Check the official onsemi ordering information table for current availability, noting that certain series variants may be discontinued or subject to change without notice. Ensure the procurement documentation matches the exact part number GBPC15005W to avoid package mismatches.

Selection Notes

Select this component for applications requiring 15 A continuous current handling with a 50 V reverse voltage rating. Consider the thermal resistance of 1.5°C/W when designing the heatsink interface. Verify that the circuit does not exceed the 300 A surge current limit during startup or fault conditions. Compare against other GBPC series ratings if higher voltage or current capabilities are required.

Part Context

This component belongs to the GBPC 12, 15, 25, 35 series of bridge rectifiers manufactured by onsemi. The series shares common mechanical dimensions and thermal characteristics, differentiated primarily by current ratings and voltage capabilities. The GBPC15005W specifically represents the 15 A, 50 V variant within this family.

Replacement Considerations

Compatible substitutes include other GBPC15005 variants from different manufacturers such as Vishay or Taiwan Semiconductor, provided they match the 15 A current, 50 V voltage, and GBPC-W package footprint. Verify terminal finish and pin compatibility before substitution.
