GBP308

Overview

The GBP308 is a single-phase bridge rectifier manufactured by Diodes Incorporated, rated for a maximum repetitive peak reverse voltage of 800V and a maximum average rectified output current of 3.0A at a case temperature of +100°C. It features a forward voltage drop of 1.05V maximum at 1.5A and a leakage current of 5µA at +25°C. The device utilizes glass passivated die construction within a GBP plastic package, offering a typical thermal resistance of 20°C/W from junction to ambient.

Feature Summary

• Glass passivated die construction provides reliable operation and low leakage current.
• Molded plastic package meets UL flammability classification 94V-0 standards.
• Lead-free finish ensures compliance with RoHS directives and environmental regulations.

Applications

• Printed circuit board mounting for general-purpose power supply applications.
• AC-to-DC conversion circuits requiring high reverse voltage blocking capabilities.
• Industrial equipment utilizing standard recovery bridge rectification.

Procurement Notes

Verify the specific ordering suffix and packaging configuration when sourcing components. Confirm that the received parts match the GBP308 designation and originate from authorized channels to ensure authenticity and adherence to specified electrical tolerances.

Selection Notes

Select this component for designs requiring an 800V reverse voltage rating with a 3A continuous current capacity. Ensure the application allows for adequate thermal management, as the device operates up to +150°C junction temperature and requires derating above +100°C case temperature.

Part Context

This part belongs to the GBP306–GBP310 series of 3A standard recovery bridge rectifiers. The series offers varying peak reverse voltage ratings of 600V, 800V, and 1000V while maintaining identical current handling and physical package dimensions for design flexibility.

Replacement Considerations

Direct substitutes include the GBP306 (600V) and GBP310 (1000V) from the same manufacturer family, provided the voltage requirements align. Other generic 3A bridge rectifiers in the GBP package may be considered if electrical parameters meet or exceed the specified limits.
