DBLS202G RDG

Bridge Rectifier Overview

The DBLS202G RDG is a single-phase standard bridge rectifier from Taiwan Semiconductor, rated for a repetitive peak reverse voltage of 100 V and an average forward current of 2 A. It utilizes the DBLS surface-mount package with four terminals and operates within a junction temperature range of -55°C to +150°C. The device supports a peak forward surge current of 50 A and exhibits a typical forward voltage of 1.15 V at 2 A. Thermal resistance values are 15 °C/W (junction-to-lead) and 40 °C/W (junction-to-ambient).

Bridge Rectifier Feature Summary

• Glass passivated chip elements provide high reliability and low leakage current.
• Molded plastic case meets UL 94V-0 flammability rating.
• Terminals are matte tin plated and solderable per J-STD-002.

Bridge Rectifier Applications

• Switching mode power supplies (SMPS)
• Adapters
• Lighting applications

Bridge Rectifier Procurement Notes

Verify the specific suffix 'RDG' against the manufacturer's official documentation to confirm tape-and-reel packaging details. Confirm RoHS compliance and halogen-free status according to IEC 61249-2-21 standards. Ensure the component matches the DBLS package outline dimensions for PCB footprint compatibility before procurement.

Bridge Rectifier Selection Notes

Select this component when a 100 V reverse voltage rating and 2 A continuous current capacity are required in a compact surface-mount form factor. Consider the thermal resistance characteristics for heat dissipation requirements in enclosed spaces. Verify if AEC-Q101 qualification is necessary for automotive applications, as indicated by the 'H' suffix in the series.

Bridge Rectifier Part Context

This part belongs to the DBLS201G through DBLS209G series, which covers reverse voltages from 50 V to 1400 V. All variants share identical mechanical dimensions and electrical characteristics except for the peak reverse voltage rating. The series is designed for general-purpose rectification in space-constrained printed circuit board assemblies.

Bridge Rectifier Replacement Considerations

Cross-reference with other manufacturers offering DBLS packaged bridge rectifiers rated at 2 A and 100 V. Ensure pinout polarity markings and terminal spacing match the existing design. Verify that substitute components meet the same thermal and surge current specifications.
