DBLS103GH

Bridge Rectifier Overview

The DBLS103GH is a single-phase bridge rectifier from the DBLS10xG series by Taiwan Semiconductor. It features a 200V repetitive peak reverse voltage (VRRM) and supports an average forward current of 1A. The device offers a peak forward surge current capability of 40A for 8.3ms half-sine waves. Electrical characteristics include a maximum forward voltage of 1.1V at 1A and a maximum reverse leakage current of 2µA at rated voltage and 25°C. It operates within a junction temperature range of -55°C to +150°C and utilizes the DBLS surface-mount package.

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 when a 200V blocking voltage is required in a compact surface-mount footprint. Ensure the circuit design accommodates the 1A continuous current limit and verify that the 40A surge rating exceeds expected inrush currents during startup conditions.

Bridge Rectifier Part Context

This part belongs to the DBLS10xG family, which provides standardized ratings across multiple voltage classes. The 'H' suffix specifically denotes AEC-Q101 qualification, distinguishing it from standard commercial grade versions while maintaining identical electrical performance and mechanical dimensions.

Bridge Rectifier Replacement Considerations

Cross-reference with other DBLS103G variants from different manufacturers. Verify pinout compatibility and ensure equivalent VRRM and IF ratings are met. Confirm package dimensions match the DBLS outline to fit existing PCB layouts.
