GBPC1202

Overview

The onsemi GBPC1202 is a single-phase glass-passivated bridge rectifier belonging to the GBPC12 series. It features an average rectified forward current (IF(AV)) of 12 A at a case temperature of 55°C and a maximum repetitive reverse voltage (VRRM) of 200 V. The device supports a non-repetitive peak forward surge current (IFSM) of 300 A for an 8.3 ms half-sine wave. 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 rated VR and 25°C. Thermal resistance from junction to case is 1.5 °C/W with a heatsink, and power dissipation reaches 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 high transient currents up to 300 A.
• Case to lead isolation voltage exceeds 2500 V for enhanced safety.
• Terminals are nickel-plated for standard GBPC packages.

Applications

• Power supply units requiring single-phase rectification
• Battery chargers and DC power adapters
• General-purpose industrial electronics

Procurement Notes

Verify the specific part number against official manufacturer documentation before procurement. Confirm that the component meets all required electrical specifications for the intended application environment. Check for any discontinuation notices or recommended alternative parts provided by the supplier. Ensure compliance with relevant safety standards and certifications applicable to the final product design.

Selection Notes

Select this component based on the 200 V reverse voltage rating and 12 A continuous current capability. Evaluate the thermal management requirements, as the junction-to-case thermal resistance is 1.5 °C/W when mounted with a heatsink. Consider the 300 A surge current rating for inrush protection needs. Verify that the operating temperature range of -55°C to +150°C aligns with the system's environmental conditions.

Part Context

The GBPC1202 is part of the broader GBPC12, 15, 25, and 35 series of bridge rectifiers from onsemi. This family shares common mechanical dimensions and mounting styles but varies in current and voltage ratings. The GBPC12 series specifically targets applications requiring 12 A average rectified current. Other variants in the series offer higher current capacities such as 15 A, 25 A, and 35 A.

Replacement Considerations

Check for discontinued status in current catalogs. Consult onsemi representatives for updated alternatives if the part is no longer recommended for new designs.
