GBU605

Overview

The Taiwan Semiconductor GBU605 is a single-phase bridge rectifier designed for general-purpose power supply applications. It features a maximum repetitive peak reverse voltage (Vrrm) of 600 V and an average forward rectified current (Io) of 6 A. The device utilizes silicon planar technology with a molded epoxy package compliant with UL flammability standards. Key electrical characteristics include a maximum non-repetitive peak forward surge current (Ifsm) of 175 A at 60 Hz, a maximum RMS isolation voltage of 4000 V, and a low leakage current of 5 μA at rated DC voltage. The component operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• High surge current capability for robust transient protection
• Low forward voltage drop for improved efficiency
• Molded epoxy package resistant to mechanical shock

Applications

• AC-DC power supplies
• Battery chargers
• Inverter circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure correct packaging and compliance status. Confirm RoHS and halogen-free designations as these may vary by production batch. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a 600 V rating and 6 A continuous current are required in a through-hole GBU package. Ensure the application's thermal management supports the specified junction temperature limits. Compare forward voltage specifications against alternative brands to optimize system efficiency under load conditions.

Part Context

This device belongs to the GBU6 series of bridge rectifiers from Taiwan Semiconductor. The series offers various voltage ratings while maintaining consistent current handling and physical dimensions. It serves as a standard solution for compact AC-to-DC conversion modules requiring reliable performance in industrial and consumer electronics.

Replacement Considerations

Direct substitutes must match the 6 A current, 600 V voltage, and GBU-4 package footprint. Verify pinout compatibility and thermal resistance values. Alternative manufacturers such as Littelfuse or Vishay offer similar GBU-series parts, but electrical parameters should be compared individually.
