HDBLS104GH

Overview

The HDBLS104GH is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features a peak repetitive reverse voltage (Vrrm) of 400 V and an average forward rectified current (Io) of 1 A. The device utilizes the DBLS surface-mount package with four pins. Key electrical parameters include a maximum non-repetitive peak forward surge current (Ifsm) of 40 A, a peak forward voltage (Vf) of 1.1 V at 1 A, and a peak reverse current (Ir) of 10 μA. The component operates within a temperature range of -55°C to +150°C junction temperature and holds AEC-Q101 automotive qualification.

Feature Summary

• High-efficiency recovery technology for improved switching performance
• Automotive-grade reliability certified under AEC-Q101 standards
• Surface-mount DBLS package design for automated placement

Applications

• Automotive power supply circuits
• General-purpose AC to DC conversion
• Battery charging systems

Procurement Notes

Verify the specific suffix 'GH' against the official manufacturer datasheet to confirm exact packaging and tape-and-reel specifications. Ensure that ordering information matches the precise part number variant required for your bill of materials, as suffixes may indicate differences in reel quantity or handling characteristics.

Selection Notes

Select this component when a 400 V rating and 1 A continuous current are required in a compact surface-mount form factor. The AEC-Q101 certification makes it suitable for automotive applications where high-temperature operation up to 150°C is necessary. Compare Vf and Ir values against alternative bridge rectifiers to ensure compatibility with thermal management constraints.

Part Context

This part belongs to the HDBLS series of high-efficiency bridge rectifiers from Taiwan Semiconductor. The series offers various voltage ratings including 200 V, 600 V, and 800 V options, all sharing similar physical dimensions and pin configurations. The HDBLS104G variant serves as the standard lead-free version, while the GH suffix typically denotes specific packaging or environmental compliance attributes defined by the manufacturer.

Replacement Considerations

Direct substitutes include other 400 V, 1 A single-phase bridge rectifiers in the DBLS package. Verify pinout compatibility and thermal resistance characteristics before substitution. Alternative parts from other manufacturers must meet or exceed the 40 A surge current capability and 150°C operating temperature limit.
