GBPC3508

Overview

The GBPC3508 is a single-phase bridge rectifier manufactured by onsemi, rated for a maximum repetitive peak reverse voltage of 800 V and an average forward current of 35 A. It features a maximum forward voltage drop of 1.1 V at rated current and operates within a junction temperature range up to 150°C. The device utilizes glass passivation for the silicon chips and is housed in an integrally molded plastic module with solderable terminals compliant with MIL-STD-202 standards. Key electrical specifications include a non-repetitive peak forward surge current of 400 A and a maximum RMS input voltage of 560 V.

Feature Summary

• Glass passivated silicon chips provide stable performance and protection against mechanical stress.
• Integrally molded heatsink design facilitates efficient thermal dissipation during operation.
• Terminals are solderable according to MIL-STD-202 Method 208 standards for reliable mounting.

Applications

• General purpose power supply circuits
• Battery charging systems
• DC motor drive interfaces

Procurement Notes

Verify the manufacturer marking matches onsemi or authorized licensees such as Fairchild Semiconductor. Confirm the part number suffix indicates the standard GBPC3508 configuration without additional functional modifications. Request the official datasheet to validate electrical parameters against specific application requirements before finalizing procurement orders.

Selection Notes

Select this component when a robust single-phase rectification solution is required for currents up to 35 A. Ensure the system voltage does not exceed the 800 V reverse voltage rating. Consider the thermal resistance characteristics if operating near the maximum junction temperature limit. Verify that the PCB layout supports the flange mount package dimensions and terminal spacing.

Part Context

This component belongs to the GBPC3 series of bridge rectifiers from onsemi. The series offers various voltage ratings while maintaining consistent current handling capabilities. It serves as a standard industrial-grade replacement for legacy bridge rectifier designs requiring high reliability and proven thermal management through integrated heatsinking structures.

Replacement Considerations

Equivalent parts include VS-GBPC3508 from Vishay and GBPC3508 from other manufacturers like Yangjie or ISC. Verify pinout compatibility and thermal resistance values when substituting. Ensure the alternative device meets the same MIL-STD-202 soldering requirements for direct board replacement.
