The 1.3 W power dissipation is rated at ambient temperature (Ta), meaning the copper pad area on the PCB sets the real thermal resistance. Input capacitance is 266 pF at Vds = 25 V, and total gate charge is 3.9 nC at Vgs = 4.5 V — both low enough that a standard GPIO pin or a small gate-driver IC can switch the MOSFET at moderate frequencies without excessive drive current.","metaTitle":"IRLML0040TRPBF N-Channel MOSFET, 40 V, 3.6 A, SOT-23","metaDescription":"IRLML0040TRPBF N-channel HEXFET MOSFET, 40 Vdss, 3.6 A continuous, 56 mOhm Rds(on) at 10 V.
