Procurement Notes

Verify the specific manufacturer designation, as Toshiba entities have undergone restructuring. Confirm the exact package marking and RoHS compliance status against the latest official datasheet. Ensure the ordering part number matches the required suffix for tape-and-reel or cut-tape quantities. Cross-reference the component against the current product lifecycle status to confirm availability and obsolescence warnings before finalizing procurement plans.

Selection Notes

Select this component when a single-channel high-side switch with moderate current capability is required. The P-Channel topology simplifies drive circuitry compared to N-Channel alternatives. Consider the 80 milliohm on-resistance for thermal management calculations at full load. The wide input voltage range allows compatibility with various battery chemistries and system rails without additional level shifting.

Part Context

This component belongs to the TCK series of load switches designed for portable applications. It complements other variants like the TCK106AG and TCK111G, which offer different current ratings and channel configurations. The series focuses on miniaturization and efficiency for modern mobile and IoT devices.

Replacement Considerations
