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. ## 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 It is ROHS3 compliant.","metaTitle":"CSD13381F4T MOSFET N-CH 12V 2.1A FemtoFET™ 3-PICOSTAR","metaDescription":"CSD13381F4T N-channel MOSFET, 12V Vdss, 2.1A continuous drain, 180mOhm Rds(on) at 4.5V.
