GBU601H

Overview

The GBU601H is a single-phase standard bridge rectifier from the Taiwan Semiconductor GBU60x series, featuring an AEC-Q101 qualification indicated by the 'H' suffix. It provides a repetitive peak reverse voltage (VRRM) of 50 V and supports a maximum average forward current (IF) of 6 A. The device withstands a surge peak forward current (IFSM) of 175 A under 8.3 ms half-sine wave conditions. Electrical characteristics include a typical forward voltage (VF) of 1.1 V at 6 A and a maximum reverse current (IR) of 5 µA at 25°C. Operating junction temperatures range from -55°C to +150°C.

Feature Summary

• AEC-Q101 qualified for automotive reliability
• High case dielectric strength of 1500 VRMS
• 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 and package type. Confirm that the 'H' suffix denotes AEC-Q101 qualification if automotive grade compliance is necessary. Check the datasheet version number to ensure alignment with current manufacturing specifications. Ensure the procurement quantity aligns with the tube packing configuration provided by the manufacturer.

Selection Notes

Select the GBU601H when a 50 V blocking capability is required alongside a 6 A continuous current rating. Consider this component for designs needing high surge current handling up to 175 A. Verify thermal management requirements against the specified junction-to-ambient thermal resistance. Ensure the operating environment temperature falls within the -55°C to +150°C junction range.

Part Context

This component belongs to the GBU601 through GBU607 series, which share identical electrical ratings except for the repetitive peak reverse voltage. The series utilizes the GBU surface-mount package and offers standardized mechanical dimensions. The 'H' variant specifically indicates AEC-Q101 qualification, distinguishing it from the standard commercial grade versions in the same physical footprint.

Replacement Considerations

Cross-reference with other GBU601 variants from different manufacturers ensuring identical 6 A current and 50 V voltage ratings. Verify pinout compatibility and physical package dimensions for direct PCB replacement. Confirm thermal performance metrics match or exceed the original junction-to-case resistance values.
