GBU604H

Overview

The Taiwan Semiconductor GBU604H is a single-phase bridge rectifier belonging to the GBU6 series, designed for general-purpose power supply applications. It features a peak repetitive reverse voltage (Vrrm) of 400 V and an average forward rectified current (Io) of 6 A at 75 °C. The device utilizes a GBU surface-mount package with four pins, measuring 22.3 mm in length and 18.8 mm in height. Key electrical characteristics include a maximum non-repetitive peak forward surge current (Ifsm) of 175 A, a peak forward voltage drop (Vf) of 1.1 V at 6 A, and a maximum reverse leakage current (Ir) of 5 μA at 400 V. The component operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• High thermal stability supporting operation up to 150 °C junction temperature
• Robust surge current handling capability for transient protection
• Low forward voltage drop for improved efficiency
• Compliant with automotive reliability standards

Applications

• Automotive electronics systems
• General-purpose AC-DC converters
• Battery chargers

Procurement Notes

Verify the specific suffix 'H' against the manufacturer's official datasheet to confirm if it denotes a specific tape-and-reel packaging variant or a distinct qualification level compared to the standard GBU604. Ensure the ordering information matches the exact RoHS compliance status and marking requirements specified in the latest product documentation.

Selection Notes

Select this component when a 6 A single-phase bridge rectifier with 400 V blocking voltage is required in a GBU surface-mount footprint. Consider the 175 A surge rating for circuits with high inrush currents. Verify that the 150 °C operating temperature range meets the thermal design constraints of the target application environment.

Part Context

The GBU604H is part of the GBU6 series from Taiwan Semiconductor, which offers various voltage ratings including 50 V, 100 V, 200 V, 400 V, 600 V, and 1000 V options. This series is characterized by its low profile and high current density, making it suitable for space-constrained designs. The 'H' suffix typically indicates a specific packaging or processing variation within the manufacturer's lineup.

Replacement Considerations

Direct pin-compatible replacements include the Diodes Incorporated GBU604 and the STMicroelectronics GBJ604, provided the forward voltage and leakage current specifications meet the circuit requirements. Always verify the mechanical dimensions and terminal plating compatibility before substitution.
