GBPC12005

Overview

The onsemi GBPC12005 is a single-phase glass-passivated bridge rectifier from the GBPC12 series, rated for a maximum repetitive reverse voltage (VRRM) of 50 V. It provides 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 for an 8.3 ms half-sine wave. The device features 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. Packaged in the GBPC-4L form factor with screw terminals, it operates within a junction and storage temperature range of -55°C to +150°C.

Feature Summary

• Integrally molded heat sink designed for very low thermal resistance to maximize heat dissipation capabilities.
• High surge overload ratings capable of handling transient currents up to 300 A.
• Provides electrical isolation with a case-to-lead voltage rating exceeding 2500 V.
• Features nickel-plated terminals suitable for standard mounting configurations.

Applications

• General-purpose AC to DC power supply rectification
• Industrial equipment power conversion circuits
• Battery charging systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct terminal finish and lead structure. Confirm that the component meets RoHS compliance requirements if restricted substances are prohibited in the target assembly. Check the datasheet discontinuation status before finalizing procurement plans to avoid obsolescence risks during production.

Selection Notes

Select this component when a 50 V blocking capability and 12 A continuous current are required in a compact through-hole package. Ensure the application can accommodate the specified thermal resistance and mounting torque limits. Verify that the operating environment stays within the -55°C to +150°C temperature range to maintain reliability and performance specifications.

Part Context

This part belongs to the GBPC12, 15, 25, and 35 series of glass-passivated bridge rectifiers manufactured by onsemi. These devices share common mechanical dimensions and thermal characteristics but differ in current ratings and voltage capabilities. The GBPC12005 specifically represents the 12 A variant within this family, offering a standardized solution for medium-power rectification tasks.

Replacement Considerations

Direct replacements include other manufacturers' GBPC12005 equivalents or Vishay GBPC12005-E4/51. Cross-reference must verify identical pinout, voltage rating, and current capacity. Mechanical compatibility requires matching the GBPC package outline and terminal spacing.
