GBPC1208W-E4/51

Overview

The GBPC1208W-E4/51 is a glass passivated single-phase bridge rectifier from Vishay General Semiconductor. It provides a maximum average forward rectified output current of 12 A and a peak repetitive reverse voltage of 800 V. The device features a typical instantaneous forward drop of 1.1 V at 6.0 A and a maximum non-repetitive peak forward surge current of 200 A. Operating junction temperature ranges from -55 °C to +150 °C, with a typical thermal resistance of 1.9 °C/W. The component utilizes the GBPC-W package, which incorporates wire leads for mounting.

Feature Summary

• Glass passivation provides mechanical strength and meets UL 94 V-0 flammability ratings
• Universal terminal design supports snap-on, wire wrap-around, or PCB mounting configurations
• High surge current capability ensures robustness against transient electrical loads

Applications

• AC/DC bridge full wave rectification in power supplies
• Rectification circuits within home appliances
• Power conversion stages in office equipment
• Industrial automation control systems

Procurement Notes

Verify the specific ordering suffix to confirm compliance with RoHS directives and commercial grade material categorization. Ensure the selected variant matches the required lead type configuration for the intended assembly process. Cross-reference the manufacturer's document number to validate the most recent revision status before finalizing procurement specifications.

Selection Notes

Select this component based on the 12 A continuous current rating and 800 V blocking voltage requirements. Evaluate the thermal management strategy using the 1.9 °C/W junction-to-case resistance value. Confirm that the operating ambient temperature remains within the specified range to maintain the rated current capacity without exceeding the maximum junction temperature limit.

Part Context

This part belongs to the GBPC12 series of single-phase bridge rectifiers manufactured by Vishay General Semiconductor. The series encompasses various voltage ratings from 50 V to 1000 V while maintaining a consistent 12 A current handling capability across different package variants.

Replacement Considerations

Compatible substitutes include the GBPC1208 and GBPC1208W models from the same Vishay family. Verify that alternative components match the 800 V reverse voltage and 12 A forward current specifications.
