GBPC3508-G

Overview

The GBPC3508-G is a single-phase bridge rectifier from Comchip Technology, rated for 35 A average forward current and 800 V repetitive peak reverse voltage. It utilizes glass passivation for enhanced stability and features an integrally molded heatsink within its plastic package. The device offers a maximum forward voltage drop of 1.1 V at rated current and supports junction temperatures up to 150°C. Electrical isolation between the case and leads exceeds 2500 V. The component is designed for general-purpose applications with solderable terminals compliant with MIL-STD-202 standards.

Feature Summary

• Glass passivated silicon construction for improved reliability
• Integrally molded heatsink for efficient thermal management
• Solderable terminals meeting MIL-STD-202 requirements

Applications

• General purpose power supply circuits
• Industrial control systems
• Military and aerospace equipment

Procurement Notes

Verify the manufacturer designation as Comchip Technology Corporation Ltd against official datasheets. Confirm the suffix -G indicates RoHS compliance. Ensure the part number matches the specific 800V rating and 35A current capacity required for the design.

Selection Notes

Select this component for high-current single-phase rectification where moderate voltage blocking is sufficient. Consider the 4-pin module package and flange mount style for board integration. Verify thermal resistance specifications if operating near maximum temperature limits.

Part Context
