GBU807H

Overview

The GBU807H is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It utilizes glass passivation for the silicon chips and is housed in a GBU-4 plastic package designed for through-hole mounting. The device supports a maximum average forward rectified current of 8.0 Amperes and offers a peak repetitive reverse voltage rating of 700 Volts. Key electrical characteristics include a maximum non-repetitive peak surge current of 200 Amperes and a maximum DC blocking voltage of 700 Volts. The component is engineered for reliable operation with a flammability classification of 94V-0.

Feature Summary

• Glass passivated silicon chips provide high reliability and long life under various operating conditions.
• Molded plastic case ensures low cost construction and meets Underwriters Laboratory Flammability Classification 94V-0.
• High surge overload capability allows handling of transient current spikes up to 200 Amperes peak.

Applications

• Printed circuit board power supply designs requiring robust rectification.
• General-purpose AC to DC conversion in industrial equipment.
• Battery charging circuits utilizing high-current requirements.

Procurement Notes

Verify the specific suffix 'H' against official Taiwan Semiconductor documentation, as standard listings often reference GBU807 without this suffix. Confirm RoHS compliance status and exact pinout configuration via the manufacturer's datasheet before ordering. Ensure the supplier provides genuine components from authorized channels to avoid counterfeit risks associated with high-demand power rectifiers.

Selection Notes

Select the GBU807H when an 8A current rating and 700V reverse voltage are required in a GBU-4 package. Compare thermal resistance values against system heat dissipation capabilities. Verify that the forward voltage drop at full load aligns with efficiency targets. Ensure the physical footprint matches the PCB layout constraints for through-hole assembly.

Part Context

This component belongs to the GBU series of single-phase bridge rectifiers from Taiwan Semiconductor. The series covers voltage ratings from 50V to 1000V with an 8A current capacity. The GBU807 variant specifically addresses applications needing 700V blocking capability. The family shares common mechanical dimensions and mounting styles for interchangeability within design limits.

Replacement Considerations

Direct substitutes include other manufacturers' GBU807 equivalents such as those from Compact Technology Corp or Shenzhen Luguang Electronics. Ensure replacement parts maintain the same 8A current rating, 700V reverse voltage, and GBU-4 package type. Verify that alternative sources offer comparable surge current ratings and thermal performance.
