GBU2508-G

Overview

The GBU2508-G is a single-phase bridge rectifier manufactured by Comchip Technology. It utilizes silicon technology with glass passivation for the junctions, housed in a GBJ-4 through-hole package measuring 30.3 mm x 4.8 mm x 19.7 mm. The device supports a maximum average forward rectified current of 25 A and a peak repetitive reverse voltage of 800 V. Key electrical parameters include a maximum forward voltage drop of 1 V at rated current, a maximum non-repetitive peak surge current of 350 A, and a maximum reverse leakage current of 10 µA. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated junctions provide high reliability and resistance to environmental variations.
• Molded plastic case ensures mechanical stability and meets UL flammability classification 94V-0.
• Designed for printed circuit board mounting with solder pin termination.

Applications

• General purpose AC to DC power supply rectification
• Battery charging circuits
• DC power input stages

Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm the exact voltage rating, as standard naming conventions may vary. Confirm RoHS compliance status directly with the supplier or datasheet, as regulatory updates occur. Ensure the GBJ-4 package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a 25 A current capacity and 800 V reverse voltage rating are required for through-hole applications. The GBJ-4 package offers robust thermal performance compared to smaller surface-mount alternatives. Verify that the 1 V forward voltage drop aligns with the system's efficiency targets under full load conditions.

Part Context

This part belongs to the GBU series of single-phase bridge rectifiers from Comchip Technology. The series is characterized by high current handling capabilities and standardized through-hole packaging suitable for industrial and consumer electronics. The GBU2508-G specifically denotes the 800 V variant within this lineup.

Replacement Considerations

Direct replacements must match the 25 A current rating, 800 V reverse voltage, and GBJ-4 package outline. Equivalent parts from other manufacturers should be verified for identical pinout configuration and thermal characteristics to ensure compatibility without PCB redesign.
