HDBLS104G

Overview

The HDBLS104G 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 a 4-SMD,鸥翼 (gull-wing) configuration. Key electrical parameters include a maximum forward voltage (Vf) of 1.3 V at 1 A and a reverse leakage current of 5 µA at 400 V. It operates within a junction temperature range of -55°C to +150°C and holds AEC-Q101 automotive qualification.

Feature Summary

• Automotive-grade reliability certified under AEC-Q101 standards for robust performance in vehicle electronics.
• High-efficiency recovery characteristics designed to minimize switching losses and improve overall circuit efficiency.
• Low-profile surface-mount DBLS packaging facilitates automated placement and compact board design.

Applications

• Automotive power supply circuits requiring AEC-Q101 compliance.
• General-purpose high-efficiency rectification in surface-mount applications.
• Compact DC power conversion systems utilizing standard bridge configurations.

Procurement Notes

Verify the specific ordering suffix when sourcing, as variants such as HDBLS104GHRD or HDBLS104GHRDG exist within the same family. Confirm that the selected part matches the required pinout and mechanical dimensions for your PCB footprint. Cross-reference the manufacturer's latest datasheet to ensure the component meets current RoHS and REACH environmental compliance requirements before finalizing procurement.

Selection Notes

Select this component for designs requiring a 400V rating with a 1A continuous current capacity in a low-profile SMD form factor. Ensure the thermal management strategy accounts for the 1.3V forward voltage drop at full load. Verify that the application environment stays within the specified -55°C to +150°C operating temperature range. Consider the AEC-Q101 qualification if the target application involves automotive systems or requires enhanced reliability standards.

Part Context

The HDBLS104G belongs to the HDBLS10xG series of high-efficiency bridge rectifiers from Taiwan Semiconductor. This series includes variants with different voltage ratings, such as the HDBLS103G (200V) and HDBLS105GH (600V). These components share similar physical packaging and general-purpose characteristics but are differentiated by their peak reverse voltage capabilities and specific recovery time specifications.

Replacement Considerations

Direct substitutes within the same series include HDBLS103G for lower voltage applications and HDBLS105GH for higher voltage requirements. Other compatible packages like DBL104G offer through-hole alternatives but differ in mounting style. Always verify pin compatibility and thermal characteristics when replacing with cross-package options.
