GBPC1204W

Overview

The onsemi GBPC1204W is a single-phase bridge rectifier from the GBPC 12 series, designed for high-current applications. It features an average rectified forward current (IF(AV)) of 12 A at a case temperature of 55°C and supports a non-repetitive peak forward surge current (IFSM) of 300 A. The device offers a maximum repetitive reverse voltage (VRRM) of 400 V with a corresponding RMS bridge input voltage of 280 V. Electrical characteristics include a maximum forward voltage drop (VF) of 1.1 V at 6.0 A and a maximum reverse current (IR) of 5.0 μA at 25°C. Thermal performance is defined by a junction-to-case thermal resistance (RθJC) of 1.5 °C/W and a power dissipation rating of 83.3 W. 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 the GBPC12 series.
• Provides isolated voltage from case to lead exceeding 2500 V.
• Terminals are silver-plated for wire-type packages, ensuring solderability per MIL-STD-208.

Applications

• General-purpose AC to DC conversion in power supplies.
• Battery charging circuits requiring robust surge handling.
• Industrial equipment utilizing single-phase bridge rectification.

Procurement Notes

Verify the specific ordering suffix 'W' corresponds to the wire lead structure variant rather than the standard pin configuration. Confirm that the procurement documentation explicitly lists the part as Pb-Free and compliant with RoHS standards. Ensure the package type matches the GBPC-W outline dimensions provided in the mechanical data sheet to guarantee correct mounting torque and lead finish specifications.

Selection Notes

Select this component when a 400 V blocking capability and 12 A continuous current are required in a compact form factor. The GBPC1204W is suitable for designs needing high surge tolerance of 300 A. Consider the thermal resistance of 1.5 °C/W when designing heatsinking solutions. Verify that the operating environment stays within the specified -55°C to +150°C junction temperature limits.

Part Context

This part belongs to the GBPC 12, 15, 25, and 35 series of glass-passivated bridge rectifiers manufactured by onsemi. The series utilizes an integrally molded heat sink design to manage thermal loads efficiently. The GBPC1204W specifically denotes the 12 A current rating and 400 V reverse voltage variant within this family of components.

Replacement Considerations

Direct replacements must match the 12 A current rating, 400 V reverse voltage, and GBPC-W package outline. Verify that alternative parts offer comparable surge current ratings of 300 A and similar thermal resistance values to ensure equivalent performance in existing circuit designs.
