Product details

FemtoFET™ N-channel — tiny footprint, real current

The Texas Instruments CSD13381F4T is an N-channel MOSFET from the FemtoFET™ series, built for switching loads up to 2.1 A continuous drain at a 12 V drain-to-source voltage. It comes in the 3-PICOSTAR package (3-XFDFN), one of the smallest surface-mount packages TI offers for a discrete MOSFET this size. The on-resistance is rated at 180 mOhm maximum at 500 mA drive at 4.5 V gate voltage, with a gate charge of 1.4 nC — meaning fast switching with minimal gate-drive overhead. The junction temperature range spans -55°C to 150°C, so it handles hot environments in portable or industrial gear.

What the 180 mOhm Rds(on) and 1.4 nC gate charge mean for your switching design

The 180 mOhm maximum on-resistance at 4.5 V gate drive sets conduction loss. The 1.4 nC gate charge at 4.5 V allows direct drive from a GPIO pin.

Active lifecycle — no obsolescence pressure for new BOMs

The CSD13381F4T is listed as Active in production status. It is ROHS3 compliant. No end-of-life notice or last-time-buy schedule is in effect. For procurement, this means the part can be specified into new designs without worrying about a short production window.

Frequently asked questions

What is the CSD13381F4T datasheet and where can I find it?

Design engineers need immediate access to full specifications including electrical characteristics, thermal data, and recommended footprint for PCB design.

What is the CSD13381F4T price in single and volume quantities?

Sourcing buyers need pricing to compare against budget and plan procurement for BOM costing.

Where can I buy CSD13381F4T in stock and what is the lead time?

Transactional intent: buyers need immediate purchase options to avoid production delays.

Is the CSD13381F4T active or obsolete? What is its lifecycle status?

Brokers and maintenance techs need to know if the part is still available or if they need to find a substitute for long-term support.

What is a suitable replacement or equivalent for CSD13381F4T?

If stock is low or part becomes unavailable, buyers and engineers need a drop-in alternative to avoid redesign.

Does CSD13381F4T have a pinout diagram and package details?

Maintenance techs and designers need pin assignment for circuit board troubleshooting and layout verification.
