D2SB05HD2G

Bridge Rectifier Overview

The D2SB05HD2G is a single-phase bridge rectifier from the Taiwan Semiconductor D2SB series, rated for a maximum average forward current of 2 A and a repetitive peak reverse voltage of 50 V. It utilizes a GBL plastic package with four internal silicon elements. The device supports a junction temperature range of -55 °C to +150 °C and withstands an 80 A non-repetitive surge current. Electrical characteristics include a maximum forward voltage of 1.1 V at 2 A and a maximum reverse leakage current of 10 µA at 25 °C. Thermal resistance values are 10 °C/W (junction-to-lead) and 47 °C/W (junction-to-ambient).

• Power adapters
• Lighting applications

Bridge Rectifier Procurement Notes

Verify that the ordering code includes the 'H' suffix to confirm AEC-Q101 qualification status. Confirm the 'G' suffix indicates compliance with RoHS directives and halogen-free requirements per IEC 61249-2-21. Ensure the specific voltage rating matches the application's reverse voltage needs within the 50V to 800V series range.

Bridge Rectifier Selection Notes

Select this component when a 2 A bridge rectifier with high surge capability is required for space-constrained PCB designs. The GBL package offers a compact footprint compared to larger through-hole options. Consider the thermal resistance parameters for heat dissipation planning in enclosed environments or high ambient temperatures.

Bridge Rectifier Part Context

This part belongs to the D2SB series, which covers voltages from 50 V to 800 V. The 'D2SB05' designation specifies the 50 V reverse voltage variant. The 'HD2G' suffix denotes AEC-Q101 qualification, halogen-free material, and RoHS compliance. Other variants in the series share identical electrical ratings but differ in peak reverse voltage specifications.

Bridge Rectifier Replacement Considerations

Direct substitutes must match the 2 A current rating, 50 V reverse voltage, and GBL package outline. Verify that alternative components also meet AEC-Q101 standards if automotive reliability is required. Check for equivalent thermal resistance and forward voltage characteristics to ensure circuit performance compatibility.
