GBPC3502-G

Overview

The GBPC3502-G is a single-phase bridge rectifier manufactured by Comchip Technology, designed for high-current applications. It features a 35 A average forward rectified current rating and supports peak repetitive reverse voltages ranging from 50 V to 1000 V, with the '02' suffix typically indicating a 200 V rating. The device utilizes glass-passivated junctions for enhanced reliability and operates within a temperature range of -55°C to +150°C. Housed in an isolated GBPC plastic package with screw mount terminals, it offers low forward voltage drop and high surge current capability, suitable for general-purpose power supply circuits.

Feature Summary

• Glass-passivated junctions provide excellent stability and reliability under varying thermal conditions.
• High surge current capability ensures robust performance during transient load events.
• Isolated mounting flange allows for direct heat sink attachment without additional insulators.
• Plastic encapsulation meets UL flammability classification standards for safety compliance.

Applications

• General-purpose AC to DC conversion in power supplies
• Battery charging circuits requiring high current handling
• DC motor drive systems and industrial control equipment

Procurement Notes

Verify the specific voltage code suffix (e.g., 02 for 200V) against the application requirements, as the base series covers multiple voltage ratings. Confirm RoHS compliance status and packaging type (bulk vs. tray) with the distributor, as these vary by production batch. Ensure the supplier provides official datasheets matching the Comchip Technology part number to avoid counterfeit components.

Selection Notes

Select this component when a 35 A continuous current rating is required in a compact, screw-mountable form factor. Compare forward voltage drop specifications at rated current to estimate thermal dissipation needs. Ensure the PCB or chassis design accommodates the GBPC package dimensions and provides adequate clearance for the isolated mounting tab. Verify that the operating ambient temperature does not exceed the maximum junction temperature limits specified in the datasheet.

Part Context

The GBPC3502-G belongs to the GBPC series of high-current bridge rectifiers, widely used in industrial and consumer electronics. Comchip Technology produces this variant alongside other manufacturers offering similar pin-compatible devices. The 'G' suffix typically denotes lead-free and halogen-free compliance, aligning with modern environmental regulations for electronic components.

Replacement Considerations

Direct replacements include GBPC3502 from Vishay, Diodes Incorporated, or onsemi. Ensure substitute parts match the 35 A current rating, 200 V reverse voltage, and GBPC package outline. Verify that alternative manufacturers specify compatible forward voltage and leakage current parameters to maintain circuit performance integrity.
