GBU30T08

Overview

The GBU30T08 is a general-purpose silicon rectifier manufactured by Diodes Incorporated, designed for high-current applications. It features an average forward rectified current of 3.0 A and a maximum repetitive peak reverse voltage of 800 V. The device utilizes a GBU package, which provides robust mechanical stability and efficient heat dissipation for through-hole mounting. Key electrical characteristics include a maximum RMS rectifier current of 3.0 A and a non-repetitive peak forward surge current capability of 150 A at 8.3 ms single half-sine-wave. Operating temperatures range from -55°C to +175°C junction temperature, ensuring reliability in demanding environments.

Feature Summary

• High thermal efficiency due to low thermal resistance junction-to-case design
• Plastic material utilized with UL flammability classification 94V-0
• Molded epoxy resists mechanical shock during operation

Applications

• AC to DC power supply rectification
• Battery charging circuits
• General-purpose rectification in industrial equipment

Procurement Notes

Verify the specific suffix designation against the manufacturer's latest datasheet to confirm exact electrical tolerances and packaging variations. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to ordering, as availability may fluctuate based on production schedules.

Selection Notes

Select this component when a through-hole solution is required for currents up to 3.0 A with reverse voltages up to 800 V. Ensure the PCB layout accommodates the GBU package dimensions and allows adequate airflow for thermal management. Compare thermal resistance values against alternative packages if space constraints are critical.

Part Context

This part belongs to Diodes Incorporated's GBU series of bridge rectifiers, widely used in power conversion modules. The series offers various voltage ratings and current capacities to suit different power supply designs. The GBU30T08 specifically addresses mid-power requirements where standard through-hole mounting is preferred over surface-mount technologies.

Replacement Considerations

Direct replacements must match the 3.0 A current rating, 800 V reverse voltage, and GBU package footprint. Verify pinout compatibility and thermal performance characteristics before substituting with parts from other manufacturers.
