GBPC1204

Overview

The onsemi GBPC1204 is a single-phase bridge rectifier from the GBPC12 series, rated for a maximum repetitive reverse voltage of 400 V and an average rectified forward current of 12 A at a case temperature of 55°C. It features a non-repetitive peak forward surge current capability of 300 A over an 8.3 ms half-sine wave. The device utilizes a standard GBPC package with screw terminals and operates within a junction temperature range of -55°C to +150°C. Electrical characteristics include a maximum forward voltage drop of 1.1 V at 6.0 A and a maximum reverse leakage current of 5.0 µA at 25°C.

Feature Summary

• Integrally molded heat sink provides very low thermal resistance for effective heat dissipation
• Offers isolated voltage from case to lead exceeding 2500 V
• Terminals are nickel-plated for durability and solderability

Applications

• AC to DC power supply input stages
• General-purpose rectification in industrial equipment
• Power factor correction circuits

Procurement Notes

Verify the specific part number against the manufacturer's official ordering information table to confirm current production status. Check for any discontinued notices or alternative packaging options such as the wire-lead variant if through-hole mounting is required. Ensure compliance with RoHS standards and verify terminal finish specifications match the application requirements before finalizing procurement.

Selection Notes

Select this component based on the required 400 V reverse voltage rating and 12 A continuous current capacity. 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. Ensure the PCB layout accommodates the screw-mount terminal spacing defined in the mechanical outline.

Part Context

This component belongs to the GBPC 12, 15, 25, and 35 series of glass-passivated bridge rectifiers manufactured by onsemi. The series offers various voltage ratings from 50 V to 1000 V while maintaining consistent physical dimensions and thermal characteristics across different current ratings. The GBPC1204 specifically addresses applications requiring moderate current handling with high voltage blocking capabilities.

Replacement Considerations

Direct replacements within the same series include GBPC1202 (200 V) and GBPC1206 (600 V). For higher current needs, consider the GBPC1504 or GBPC2504 models. Wire-lead equivalents are available as GBPC1204W. Verify pinout compatibility and thermal management requirements when substituting.
