DBLS105GHC1G

Bridge Rectifier Overview

The DBLS105GHC1G is a single-phase bridge rectifier from the Taiwan Semiconductor DBLS105G series, rated for a repetitive peak reverse voltage of 600 V and an average forward current of 1 A. It utilizes a surface-mount DBLS package with four terminals and operates within a junction temperature range of -55°C to +150°C. The component features a maximum non-repetitive peak forward surge current of 40 A and a typical forward voltage of 1.1 V at 1 A. Reverse leakage current is specified at 2 µA at 25°C. This variant includes the 'H' suffix indicating AEC-Q101 automotive qualification.

Bridge Rectifier Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• High surge current capability for robust operation
• Molded plastic construction with UL 94V-0 flammability rating

Bridge Rectifier Applications

• Switching mode power supplies (SMPS)
• Power adapters
• Lighting applications

Bridge Rectifier Procurement Notes

Verify the specific ordering code against official Taiwan Semiconductor documentation to confirm the presence of the AEC-Q101 qualification indicated by the 'H' suffix. Ensure the DBLS package dimensions and polarity markings align with the target PCB layout requirements before finalizing procurement specifications.

Bridge Rectifier Selection Notes

Select this component when a surface-mount bridge rectifier with automotive-grade reliability is required for low-current AC-to-DC conversion. The 600 V rating suits general-purpose mains or intermediate bus voltages. Verify thermal management needs based on the junction-to-ambient resistance of 40 °C/W for the specific mounting environment.

Bridge Rectifier Part Context

This part belongs to the DBLS10xG family of standard bridge rectifiers manufactured by Taiwan Semiconductor. The series covers voltage ratings from 50 V to 1000 V in a compact DBLS surface-mount package. The '105' designation specifically denotes the 600 V reverse voltage capability within this standardized product line.

Bridge Rectifier Replacement Considerations

Cross-reference with other DBLS105G variants from different manufacturers that share the same electrical ratings and DBLS footprint. Confirm that any substitute also meets AEC-Q101 requirements if automotive compliance is mandatory for the application.
