GBPC1204-E4/51

Overview

The Vishay GBPC1204-E4/51 is a glass passivated single-phase bridge rectifier in the GBPC series. It provides a maximum average forward rectified output current (IF(AV)) of 12 A and a peak forward surge current (IFSM) of 200 A. The device supports a maximum repetitive peak reverse voltage (VRRM) of 400 V, with a corresponding maximum RMS voltage of 280 V and DC blocking voltage of 400 V. Electrical characteristics include a typical instantaneous forward drop (VF) of 1.1 V at 6.0 A and a maximum reverse DC current (IR) of 5 μA at rated voltage. Thermal resistance from junction to case (RθJC) is 1.9 °C/W. Operating temperatures range from -55 °C to +150 °C.

Feature Summary

• Glass passivation protects junctions against mechanical stresses
• Universal mounting terminals support snap-on, wire wrap-around, or PCB installation
• High surge current capability for robust transient handling
• Low thermal resistance enables efficient heat dissipation

Applications

• AC/DC bridge full wave rectification for power supplies
• Home appliances requiring general purpose rectification
• Office equipment power circuits
• Industrial automation applications

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm RoHS compliance status via the E4 suffix designation. Ensure terminal plating matches application requirements, as faston lugs are nickel-plated while wire leads are silver-plated. Validate that the selected package variant aligns with the required mounting method and lead configuration.

Selection Notes

Select this component when a 12 A continuous current rating and 400 V reverse voltage withstand capability are required. Consider the 1.9 °C/W thermal resistance for heatsink design calculations. Verify that the 200 A non-repetitive surge rating meets circuit fault conditions. Ensure the operating temperature range of -55 °C to +150 °C accommodates the environmental conditions of the target assembly.

Part Context

This part belongs to the Vishay GBPC12 family of single-phase bridge rectifiers. The series includes variants with different voltage ratings (50 V to 1000 V) and current ratings (12 A to 35 A). All members share the same GBPC plastic package and mechanical dimensions, differing primarily in their electrical breakdown and conduction parameters.

Replacement Considerations

Direct replacements within the same Vishay GBPC12 series include GBPC1202-E4/51 (200 V), GBPC1206-E4/51 (600 V), and GBPC1208-E4/51 (800 V). Cross-manufacturer equivalents must match the 12 A IF(AV), 400 V VRRM, and GBPC footprint. Verify thermal resistance and surge current capabilities before substitution.
