GBPC1206

Overview

The onsemi GBPC1206 is a single-phase bridge rectifier from the GBPC 12, 15, 25, and 35 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 600 V. The device has a non-repetitive peak forward surge current (IFSM) rating of 300 A for an 8.3 ms single half-sine-wave pulse. 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 is 83.3 W. Operating and storage temperatures range from -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 nickel-plated for the standard GBPC package.

Applications

• General-purpose AC/DC conversion in industrial equipment.
• Power supply units requiring high surge current handling.
• Applications necessitating robust thermal management via screw mounting.

Procurement Notes

Verify the specific part number against the manufacturer's discontinuation list before procurement. The datasheet indicates that certain variants within the GBPC series may be discontinued or not recommended for new designs. Confirm availability through authorized distributors and ensure compliance with RoHS standards as these devices are Pb-Free. Check for updated ordering information on the official manufacturer website.

Selection Notes

Select the GBPC1206 when a 600 V blocking voltage and 12 A continuous current are required. Ensure the application can maintain the case temperature at or below 55°C to achieve the rated IF(AV). For wire-lead applications, consider the GBPC-W variant instead of the standard screw-mount GBPC package. Verify that the PCB layout accommodates the 4-pin GBPC footprint and allows for adequate heatsinking to manage the 83.3 W power dissipation.

Part Context

The GBPC1206 belongs to the GBPC 12, 15, 25, and 35 series of glass-passivated bridge rectifiers manufactured by onsemi. This series offers various voltage ratings from 50 V to 1000 V and current ratings from 12 A to 35 A. The GBPC1206 specifically addresses the 600 V requirement within the 12 A current class, sharing common mechanical dimensions and thermal characteristics with other members of the family.

Replacement Considerations

Direct replacements must match the 600 V VRRM, 12 A IF(AV), and GBPC package type. Other manufacturers offering equivalent specifications should be evaluated for thermal resistance and surge current capabilities. Note that the GBPC1208 is listed as discontinued in the provided documentation; therefore, it is not a valid replacement option.
