GBU604-K

Overview

The GBU604-K is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, rated for an average forward current of 6A. It features a repetitive peak reverse voltage (VRRM) of 400V and is housed in a GBU surface-mount package. The device supports a maximum junction temperature of 150°C and offers a surge peak forward current capability of 175A under standard half-sine wave conditions. Electrical characteristics include a typical forward voltage of 1.0V at 3A and a low reverse leakage current below 0.1μA.

Feature Summary

• High case dielectric strength of 1500VRMS
• Ideal for printed circuit board mounting
• Halogen-free according to IEC 61249-2-21

Applications

• Switching mode power supply (SMPS)
• Adapters
• Lighting application

Procurement Notes

Verify the specific ordering code matches the required voltage rating, as the suffix 'x' defines values from 400V to 1000V across the series. Confirm RoHS compliance and halogen-free status against project specifications. Ensure the purchasing documentation references the correct datasheet version E2103 to validate thermal resistance and electrical limits.

Selection Notes

Select this component when a 6A bridge rectifier with a 400V blocking voltage is required for PCB-mounted designs. Consider the GBU package dimensions and the 0.56 N⋅m maximum mounting torque during mechanical layout. Evaluate thermal performance using the specified junction-to-case thermal resistance if operating near the 150°C maximum junction temperature limit.

Part Context

This part belongs to the GBU604-K through GBU607-K series produced by Taiwan Semiconductor Corporation. The series shares identical physical packaging and current ratings, differing only in their maximum repetitive peak reverse voltage capabilities ranging from 400V to 1000V. The GBU604-K specifically addresses applications requiring lower voltage blocking thresholds within this standardized form factor.

Replacement Considerations

Direct substitutes must match the 6A current rating, 400V minimum reverse voltage, and GBU package outline. Verify that alternative components meet the same UL Recognized File # E-326243 requirements and maintain comparable thermal resistance values for equivalent heat dissipation performance.
