HDBL105GH

Overview

The HDBL105GH is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, designed for high-efficiency recovery applications. It features a peak repetitive reverse voltage (Vrrm) of 600 V and an average forward current (If) of 1 A. The device exhibits a maximum non-repetitive peak forward surge current (Ifsm) of 50 A and a typical reverse leakage current (Ir) of 5 µA at rated voltage. The forward voltage drop (Vf) is specified at 1.7 V. Operating within a temperature range from -55°C to +150°C, it utilizes a DBLS-4 surface-mount package with dimensions of 8.51 mm in length, 6.5 mm in width, and 2.6 mm in height.

Feature Summary

• Glass passivated chip junction construction ensures reliable operation under harsh electrical conditions.
• High efficiency recovery characteristics optimize performance in switching power supply circuits.
• Compliant with AEC-Q101 automotive standards for enhanced reliability and durability.

Applications

• Automotive electronics systems requiring AEC-Q101 qualified components
• General-purpose AC to DC conversion in compact power supplies
• Battery charging circuits in mobile and portable devices

Procurement Notes

Verify the specific suffix 'H' on the packing code to confirm AEC-Q101 qualification status, as this designation indicates compliance with automotive reliability standards. Ensure the component meets JESD 201 class whisker test requirements when applicable. Cross-reference the manufacturer part number with official datasheets to confirm package type and electrical ratings before integration into production designs.

Selection Notes

Select the HDBL105GH for applications requiring a 600 V reverse voltage rating and 1 A continuous current capability in a compact surface-mount form factor. Consider its 150°C maximum operating temperature for environments with elevated thermal loads. Evaluate the 1.7 V forward voltage drop against system efficiency targets. Confirm that the DBLS-4 package footprint aligns with the printed circuit board layout constraints.

Part Context

This component belongs to the DBLS105G series of high-efficient recovery bridge rectifiers from Taiwan Semiconductor. The series is engineered to provide low forward voltage and fast recovery times, making it suitable for modern power management solutions. The HDBL105GH variant specifically incorporates automotive-grade qualification markers, distinguishing it from standard industrial counterparts within the same product family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative bridge rectifiers based on matching Vrrm, If, Vf, and package dimensions. Ensure any replacement meets the same AEC-Q101 and environmental compliance standards if required by the application.
