GBPC108-E4/51

Overview

The GBPC108-E4/51 is a glass passivated single-phase bridge rectifier manufactured by Vishay General Semiconductor. It utilizes the GBPC1 case style and provides an average forward rectified output current of 3.0 A at a case temperature of 60 °C, or 2.0 A at an ambient temperature of 25 °C. The component features a maximum repetitive peak reverse voltage (VRRM) of 800 V and a maximum DC blocking voltage of 800 V. It supports a peak forward surge current of 60 A and exhibits a typical junction capacitance of 21 pF per diode. The device operates within a junction and storage temperature range of -55 °C to +150 °C.

Feature Summary

• Glass passivation protects junctions against mechanical stresses
• High case dielectric strength for reliable operation
• Silver plated leads ensure solderability per J-STD-002

Applications

• AC/DC bridge full wave rectification for switching power supplies
• Home appliances
• Office equipment
• Industrial automation applications

Procurement Notes

Verify the specific ordering suffix E4/51 to confirm RoHS compliance and bulk paper box packaging. Confirm that the base part number corresponds to the 800 V rating variant within the GBPC10x series. Ensure procurement channels provide the official Vishay datasheet document number 88611 for technical validation prior to integration.

Selection Notes

Select this component when an 800 V reverse voltage rating is required for single-phase bridge rectification. Verify thermal management requirements based on the 12 °C/W thermal resistance from junction to ambient. Ensure the application current does not exceed 2.0 A at 25 °C ambient without derating, or remains within 3.0 A limits at 60 °C case temperature.

Part Context

This component belongs to the GBPC10x series of glass passivated single-phase bridge rectifiers. The series includes variants with reverse voltage ratings ranging from 50 V to 1000 V. All members share the same GBPC1 package dimensions and electrical characteristics regarding current handling and surge capability, differing primarily in their maximum repetitive peak reverse voltage specifications.

Replacement Considerations

Cross-reference other manufacturers offering GBPC1 packaged bridge rectifiers with identical 800 V VRRM and 3 A IF(AV) ratings. Verify pinout compatibility, specifically the positive lead identification via the beveled corner marking.
