HDBL104G

Overview

The HDBL104G 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 a DBLS surface-mount package with four pins, measuring 8.51 mm in length and 2.6 mm in height. Key electrical parameters include a maximum peak non-repetitive forward surge current (Ifsm) of 40 A, a peak forward voltage (Vf) of 1.1 V at 1 A, and a maximum peak reverse current (Ir) of 10 μA. It operates within a temperature range of -55°C to +150°C junction temperature.

Feature Summary

• High-efficiency rectification utilizing glass passivation technology for stable performance.
• Automotive-grade reliability certified under the AEC-Q101 standard.
• Compact surface-mount DBLS packaging designed for automated assembly processes.

Applications

• AC-DC power supply circuits requiring compact form factors.
• General-purpose rectification in consumer electronic devices.
• Automotive electronics systems adhering to automotive qualification standards.

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm exact package variations or tape-and-reel specifications. Confirm RoHS compliance status and REACH registration details directly with the supplier prior to procurement. Ensure the component meets the required AEC-Q101 automotive qualification if intended for automotive applications. Cross-reference the full part number with the latest datasheet to avoid discrepancies in pinout or thermal characteristics.

Selection Notes

Select this component when a 1 A single-phase bridge rectifier with 400 V blocking capability is required in a low-profile surface-mount configuration. The DBLS package offers space savings compared to through-hole alternatives like the DBL series. Consider the 40 A surge current rating for transient protection needs. Verify that the 1.1 V forward voltage drop aligns with the efficiency requirements of the target circuit design.

Part Context

This component belongs to the HDBLS104G series of high-efficiency bridge rectifiers from Taiwan Semiconductor. It shares core electrical specifications with variants such as HDBLS104GHRD but may differ in packaging or trailing suffixes indicating specific reel configurations. The series is designed to replace older through-hole designs in modern PCB layouts while maintaining robust electrical performance.

Replacement Considerations

The DBL104G serves as a through-hole alternative with identical electrical ratings but different mounting requirements. For surface-mount replacements, verify compatibility with the DBLS footprint. Other manufacturers offering 1 A, 400 V SMD bridge rectifiers in similar packages may require verification of pinout alignment and thermal resistance values before substitution.
