GBPC3502W-G

Overview

The GBPC3502W-G is a single-phase bridge rectifier manufactured by Comchip Technology, designed for high-current applications. It features an average forward current of 35 A and a maximum repetitive peak reverse voltage of 200 V. The device utilizes glass passivation for terminal protection and offers a low forward voltage drop of 1.1 V at rated current. It supports a non-repetitive peak forward surge current of 400 A and operates within a junction temperature range of -55°C to +150°C. The component is housed in a plastic GBPC package with screw mounting terminals, providing case-to-terminal isolation.

Feature Summary

• Glass passivated die construction for enhanced terminal protection and reliability
• Metal base design integrated into the package for efficient heat dissipation
• High surge overload capability to withstand transient current spikes
• Electrical isolation between the case and terminals for safety

Applications

• AC-DC power supply circuits requiring high current output
• Battery charging systems for industrial equipment
• Inverter and converter input stages

Procurement Notes

Verify the specific manufacturer source, as the GBPC series is produced by multiple vendors including Diodes Incorporated and onsemi. Confirm that the suffix 'G' denotes RoHS compliance and lead-free finish as per standard industry definitions for this part family. Ensure the datasheet matches the required electrical parameters for your specific circuit design before finalizing procurement.

Selection Notes

Select this component when a 35 A continuous current rating and 200 V blocking voltage are required in a screw-mountable package. Compare the thermal resistance characteristics against alternative packages like KBPC if space constraints exist. Verify that the 1.1 V forward voltage drop aligns with the efficiency requirements of the target application.

Part Context

The GBPC3502W-G belongs to the GBPC series of single-phase bridge rectifiers, which are widely used in general-purpose power conversion. This series is characterized by its robust plastic encapsulation and metal base for thermal management. Similar parts in the series include variants with different voltage ratings such as GBPC3504 or GBPC3506, maintaining the same 35 A current capacity.

Replacement Considerations

Direct substitutes include GBPC3502 from other manufacturers such as Diodes Incorporated or onsemi, provided the pinout and mechanical dimensions are identical. Cross-reference the datasheet for any differences in thermal resistance or isolation voltage ratings.
