DBLS203GH

Bridge Rectifier Overview

The DBLS203GH is a single-phase standard bridge rectifier from the DBLS201G–DBLS209G series by Taiwan Semiconductor. It features a 2A average forward current (IF) and a 50A peak non-repetitive forward surge current (IFSM). The device has a repetitive peak reverse voltage (VRRM) of 200V. It operates within a junction temperature range of -55°C to +150°C. The component utilizes a DBLS surface-mount package with four pins. Electrical characteristics include a typical forward voltage of 1.15V at 2A and a maximum reverse current of 2µA at 25°C. Thermal resistance values are 15°C/W junction-to-lead and 40°C/W junction-to-ambient.

Bridge Rectifier Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• High surge current capability with molded plastic construction
• Low cost design suitable for printed circuit board mounting

Bridge Rectifier Applications

• Switching mode power supplies (SMPS)
• Power adapters
• Lighting applications

Bridge Rectifier Procurement Notes

Verify the specific ordering code matches the required voltage rating and packaging format. Confirm AEC-Q101 qualification status if automotive compliance is mandatory. Check datasheet revisions for potential parameter updates before finalizing procurement specifications.

Bridge Rectifier Selection Notes

Select this component based on the 200V reverse voltage requirement and 2A continuous current capacity. Ensure the DBLS package footprint aligns with the PCB layout constraints. Consider thermal management requirements given the specified junction-to-ambient thermal resistance values under expected load conditions.

Bridge Rectifier Part Context

This part belongs to the DBLS201G through DBLS209G family, which covers voltage ratings from 50V to 1400V. The 'H' suffix indicates AEC-Q101 qualification. All variants share identical electrical parameters except for the peak reverse voltage rating.

Bridge Rectifier Replacement Considerations

Direct substitutes within the same series include DBLS201GH, DBLS202GH, DBLS204GH, etc., differing only in VRRM ratings. Verify that alternative components match the 2A IF and DBLS package dimensions for pin compatibility.
