GBPC3510-G

Overview

The GBPC3510-G is a single-phase bridge rectifier manufactured by Comchip Technology, designed for general-purpose power conversion applications. It features a molded plastic body with an integrated heat sink to minimize thermal resistance and maximize heat dissipation efficiency. The device utilizes silicon epitaxial planar chips and offers a peak average forward current of 35 A with a maximum repetitive peak reverse voltage of 1000 V. Key electrical parameters include a peak forward voltage of 1.1 V at rated current and a non-repetitive peak forward surge current capability of up to 400 A. The component operates within a temperature range of -55 °C to +150 °C junction temperature and includes UL certification (E258596) for safety compliance.

Feature Summary

• Integrated molded heat sink design provides low thermal resistance for efficient heat dissipation.
• High surge overload rating supports transient current loads from 300 A to 400 A.
• Isolated case-to-lead insulation voltage exceeds 2500 V for enhanced safety.
• Silver-plated terminals on the GBPC-W variant ensure reliable solderability per MIL-STD-202 Method 208.

Applications

• General-purpose AC to DC power supply rectification
• Battery charging circuits in industrial equipment
• DC motor drive power stages

Procurement Notes

Verify that the specific suffix matches the required terminal finish; the GBPC-W variant specifies silver plating while standard GBPC uses nickel. Confirm UL file number E258596 is present on documentation for regulatory compliance. Ensure ordering specifications align with the through-hole mounting requirements and torque limits of 20 in-lbs for secure installation.

Selection Notes

Select this component when a 35 A continuous current rating and 1000 V blocking voltage are required in a compact square package. Consider the GBPC-W variant if silver-plated leads are necessary for specific soldering processes or corrosion resistance. Evaluate thermal management needs based on the 1.5 °C/W junction-to-case thermal resistance characteristic for proper heatsink sizing.

Part Context

This part belongs to the GBPC series of single-phase bridge rectifiers, characterized by high current density and robust mechanical construction. It serves as a discrete semiconductor solution for converting alternating current to direct current in medium-power electronic systems. The series is widely utilized in applications requiring reliable performance under high thermal stress and electrical load conditions.

Replacement Considerations

Direct substitutes include the KBPC3510 and GBPC3510GI. Verify pinout compatibility and thermal resistance values before substitution. Ensure the replacement part meets the same 1000 V reverse voltage and 35 A forward current ratings to maintain circuit integrity.
