HDBL101GH

Overview

The HDBL101GH is a high-efficient bridge rectifier from the Taiwan Semiconductor HDBL101G series, designed for surface-mount applications. It features a glass passivated chip junction and utilizes molded plastic construction within a DBL package. The device supports a repetitive peak reverse voltage (VRRM) of 50 V and an average forward current (IF) of 1 A. It offers a peak forward surge current capability of 50 A and operates across a junction temperature range of -55°C to +150°C. The 'H' suffix indicates that this specific variant is qualified under the AEC-Q101 automotive standard.

Feature Summary

• Glass passivated chip junction ensures reliable low-cost construction utilizing molded plastic technique
• AEC-Q101 qualification confirms suitability for automotive electronic environments
• High surge current capability with UL recognition file E-326854

Applications

• Switching mode power supply (SMPS)
• Adapters
• Lighting application

Procurement Notes

Verify the component marking code matches HDBL101G to confirm the 50V rating. Ensure the presence of the 'H' designation in the part number or datasheet confirmation to validate AEC-Q101 qualification status. Confirm the DBL package type and matte tin plated leads meet the required solderability standards per J-STD-002 before integration into the assembly process.

Selection Notes

Select the HDBL101GH when a 50 V reverse voltage rating and 1 A continuous forward current are required for PCB-mounted designs. This component is appropriate for circuits demanding AEC-Q101 compliance and high surge tolerance up to 50 A. Consider thermal resistance values of 15 °C/W (junction-to-lead) for heat dissipation planning in enclosed adapter or lighting enclosures.

Part Context

This component belongs to the HDBL10xG series, which covers voltage ratings from 50 V to 1000 V. The HDBL101G specifically denotes the 50 V variant within this family. The series shares common mechanical data, including the DBL package and glass passivation technology, while differing primarily in their maximum repetitive peak reverse voltage specifications.

Replacement Considerations

Direct substitutes include other HDBL101G variants from different manufacturers offering identical 1 A, 50 V specifications in the DBL package. Verify that any replacement maintains AEC-Q101 qualification if automotive reliability is required. Ensure the alternative component meets the same 50 ns reverse recovery time and 50 A surge current capabilities.
