Active N-channel 600 V MOSFET in the TO-220 footprint
The SIHP25N60EFL-BE3: The 146 mOhm maximum on-resistance at 12.5 A with a 10 V gate drive sets the conduction loss budget for the design. Housed in the through-hole TO-220-3 package (supplier device package TO-220AB), this is a standard footprint for board-level power stages in switch-mode supplies, motor drives, and high-voltage DC-DC converters.
Gate drive and switching loss — what the numbers mean
Total gate charge is 75 nC at Vgs = 10 V, and input capacitance is 2274 pF measured at Vds = 100 V. These two numbers drive the gate-driver selection: a driver sourcing 1 A charges the gate in roughly 75 ns, but the actual switching loss depends on the Miller plateau and the driver's sink current. The 75 nC figure is moderate for a 600 V / 25 A device — a typical 2 A gate driver handles it without excessive crossover loss. The maximum gate-source voltage is ±30 V, and the recommended drive voltage for minimum Rds(on) is 10 V.
