Gate charge is 0.959 nC at 4.5 V, and input capacitance is 198 pF at 10 V drain-source. These low values make the CSD25483F4 suitable for switching frequencies up to several hundred kHz without significant drive losses. ## Temperature grade and deployment context Rated for junction temperatures from -55 to 150 °C, this MOSFET fits automotive under-hood, industrial motor-drive, and outdoor telecom environments where ambient temperatures exceed 85 °C. The 500 mW power dissipation at 25 °C ambient (Ta) sets the thermal budget; in a 125 °C ambient the allowable dissipation derates to roughly 200 mW, so the actual continuous current must be reduced accordingly. ## Package and footprint — the 3-PICOSTAR The 3-XFDFN (3-PICOSTAR) is a 1.0 mm × 0.6 mm body with 0.35 mm pitch — one of the smallest discrete MOSFET packages available. The centre pad is the drain; the two outer pads are gate and source. The small footprint suits space-constrained designs like wearables, smartphone sub-circuits, and compact IoT modules, but the 0.35 mm pitch requires careful solder-paste stencil design and a controlled reflow profile. ## Lifecycle and compliance It is ROHS3 compliant and Pb-free, meeting the Restriction of Hazardous Substances directive for lead, mercury, cadmium, and other controlled substances.","metaTitle":"CSD25483F4 NexFET P-Channel MOSFET, 20 V, 1.6 A, 205 mOhm","metaDescription":"Texas Instruments CSD25483F4 P-Channel MOSFET, 20 V drain-source, 1.6 A continuous drain, 205 mOhm Rds(on) at 8 V. 3-PICOSTAR package.
