24 V, 38 A N-channel in DPAK — STripFET™ III generation
The 13.5 mOhm maximum Rds(on) at 10 V gate drive is specified at 19 A, which gives a conduction loss of roughly 2.6 W at that current — a figure that must be checked against the 40 W package dissipation limit and the thermal impedance of the board. The gate charge is 24 nC at 10 V, a moderate value that keeps switching losses manageable for a 38 A rated device; the driver must supply this charge per switching cycle. The input capacitance is 1070 pF at 25 V drain-source, which influences the gate drive rise time and the switching speed.
