SDB105-TP

Bridge Rectifier Overview

The SDB105-TP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It utilizes glass passivated chip junctions and operates within a temperature range of -55°C to +150°C. The device supports an average rectified forward current of 1A at 40°C and withstands a peak repetitive reverse voltage of 400V. Key electrical characteristics include a maximum reverse current of 10µA at 125°C, a typical forward voltage of 1.1V at 0.5A, and a non-repetitive peak surge current of 30A for an 8.3ms half-sine wave. It is housed in the low-profile SDBL-1 surface mount package.

Bridge Rectifier Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase from the manufacturer. Counterfeit components are prevalent; ensure traceability and compliance with quality standards. Confirm RoHS compliance via the "P" suffix designation. Request official datasheets and material declarations prior to procurement to validate specifications and packaging details.

Bridge Rectifier Selection Notes

Select this component for applications requiring a 400V blocking voltage and 1A continuous current capability in a compact surface mount footprint. Ensure thermal management accounts for the specified thermal resistance values. Verify that the operating ambient temperature remains within the rated limits to maintain current carrying capacity without derating.

Bridge Rectifier Part Context

This part belongs to the SDB101L through SDB107L series of 1 Amp single-phase bridge rectifiers. The series offers varying peak repetitive reverse voltage ratings from 50V to 1000V while maintaining identical physical dimensions and current handling capabilities. The SDB105-TP specifically provides a 400V rating within this standardized family.

Bridge Rectifier Replacement Considerations

Compatible replacements within the same series include SDB104L-TP (200V) and SDB106L-TP (600V), provided voltage requirements align. Other manufacturers offering equivalent 1A, 400V SMD bridge rectifiers in similar packages may be considered if pinout compatibility and thermal characteristics match.
