HDBLS106G

Overview

The HDBLS106G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, designed for surface-mount applications. It features an average forward current (If) of 1 A and a peak repetitive reverse voltage (Vrrm) of 800 V. The device exhibits a maximum forward voltage drop (Vf) of 1.7 V at the rated current and a peak non-repetitive forward surge current (Ifsm) capability of 50 A. Reverse leakage current (Ir) is specified at 5 µA when tested at 800 V. The component operates within a junction temperature range of -55°C to +150°C and is housed in a compact DBLS-4 package with dimensions of 8.51 mm in length, 6.5 mm in width, and 2.6 mm in height.

Feature Summary

• Glass passivated junction construction ensures reliable operation under high-temperature conditions.
• Molded plastic technique provides low-cost construction suitable for automated printed circuit board assembly.
• High surge current capability supports transient load requirements in power supply circuits.

Applications

• Adapters and chargers requiring efficient AC-to-DC conversion
• General-purpose power supplies utilizing surface-mount technology
• Battery charging circuits for consumer electronics

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging configurations. Ensure that any suffix variations do not alter the fundamental pinout or voltage ratings required for the target design. Cross-reference the part number with authorized distributors to confirm current availability status and lead times before finalizing procurement plans.

Selection Notes

Select this component for designs requiring a compact 800 V bridge rectifier with a 1 A continuous current rating. The DBLS-4 package is appropriate for space-constrained PCB layouts. Verify that the thermal management strategy accommodates the 1.7 V forward voltage drop at full load to maintain junction temperatures within the specified -55°C to +150°C operating range.

Part Context

This component belongs to the HDBLS series of glass-passivated high-efficiency bridge rectifiers from Taiwan Semiconductor. The series offers various voltage ratings while maintaining a consistent 1 A current capacity and low-profile SMD footprint. It serves as a standard solution for replacing through-hole rectifiers in modern surface-mount power supply designs.

Replacement Considerations

Direct substitutes include the HDBL106G and HDBLS106GRDG. Verify pin compatibility and thermal characteristics before substitution.
