Procurement Notes

This component is officially listed as obsolete or discontinued by the manufacturer. Availability is restricted, and sourcing may be limited to surplus channels. Verify part authenticity and condition carefully when procuring from third-party distributors due to the end-of-life status.

Selection Notes

Select this component only if legacy compatibility with the 20V P-Channel specification is required. Consider modern equivalents from the same family or alternative manufacturers offering active status and improved availability. Ensure the SOT-23 footprint matches the existing design constraints.

Part Context

The SI6953DQ belongs to the SI6 series of MOSFETs produced by Vishay / Siliconix. This series utilizes TrenchFET technology to provide efficient switching capabilities. The specific model represents a compact solution for low-voltage power management tasks in consumer and industrial electronics.

Replacement Considerations

Verify cross-references such as SI6953DD-T1-GE3 for identical specifications. Consult official substitution guides for updated components with active manufacturing status.
