GBU607

Overview

The GBU607 is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, designed for general-purpose power supply applications. It features an average forward rectified current of 6A and a maximum repetitive peak reverse voltage of 1000V. The device utilizes glass passivation to protect the junctions against mechanical stress and humidity. Key electrical parameters include a maximum non-repetitive peak forward surge current of 175A at 60Hz, a typical reverse current of less than 0.1μA, and a maximum DC blocking voltage of 1000V. The component operates within a temperature range of -55°C to +150°C junction temperature and is housed in a GBU (4-pin) through-hole package.

Feature Summary

• Glass passivated junctions provide protection against mechanical stress and environmental humidity
• High case dielectric strength rated at 1500 VRMS for enhanced isolation safety
• Capable of handling high surge currents with a peak rating of 175A
• Low leakage current characteristics with typical IR below 0.1μA

Applications

• Printed circuit board mounting for AC-DC conversion
• General-purpose power supply units
• Battery chargers requiring 1000V reverse voltage capability

Procurement Notes

Verify component authenticity by checking for Taiwan Semiconductor branding and part markings on the GBU package. Confirm RoHS compliance and halogen-free status according to IEC 61249-2-21 standards. Ensure the supplier provides valid traceability documentation matching the manufacturer's specifications for quality assurance.

Selection Notes

Select this component when a 6A continuous current and 1000V reverse voltage rating are required in a through-hole configuration. Consider the GBU package dimensions for PCB layout constraints. Verify thermal management requirements as the junction temperature can reach 150°C during operation.

Part Context

The GBU607 belongs to the GBU series of single-phase bridge rectifiers from Taiwan Semiconductor. This series offers various voltage ratings while maintaining consistent current and packaging characteristics. The GBU607 specifically addresses applications needing high reverse voltage tolerance alongside standard 6A current handling capabilities.

Replacement Considerations

Compatible alternatives include other 6A 1000V bridge rectifiers in the GBU package such as the GBU607H or generic equivalents from other manufacturers. Ensure pinout compatibility and verify that substitute components meet the same 1500 VRMS dielectric strength and surge current requirements.
