Product details

25 V, 50 A N-channel — what this OptiMOS part delivers

The on-resistance sits at 5.1 mOhm maximum when driven with 10 V on the gate — a figure that keeps I²R losses low in a 50 A rail. Gate charge is 25 nC at 5 V drive, so the driver doesn't work hard to switch it.

Junction temperature spans -55 to 175 °C, which puts it in the industrial and automotive temperature grade. That 175 °C ceiling means it can sit next to a hot inductor or inside an engine-bay enclosure without derating the junction limit. The maximum gate-source voltage is ±20 V, giving margin against ringing on long gate traces. Input capacitance is 3110 pF at 15 V drain bias — a moderate number that doesn't force a high-current gate driver but still needs a clean layout to avoid Miller turn-on.

Surface-mount in a TO-252-3 (DPak) with a single tab for the drain connection. The supplier device package is PG-TO252-3-23. The tab is the drain terminal, so the PCB copper plane under the part serves as both electrical connection and heatsink. For 50 A continuous, that tab needs a decent copper area — don't rely on the package alone to shed 94 W of dissipation. The drive voltage range is 4.5 V to 10 V for achieving the rated Rds(on); 5 V logic-level gate drive will work, but 10 V gives the lowest on-resistance.
