The STP50NF25: The 69 mOhm Rds(on) at 22 A and 10 V is the conduction-loss figure for thermal design. Input capacitance Ciss is 2670 pF at 25 V drain-source, which sets the switching energy per cycle. Together with the gate charge, this gives a designer the numbers to estimate cross-conduction losses and dead-time requirements in a half-bridge topology.
