100 V N-channel in a 2x2 mm PowerFlat — what it fits
The PowerFlat™ (2x2) package keeps the footprint small — about the size of a grain of rice — which matters when board space is tight.
Gate charge and switching speed — the drive side
Total gate charge is 7.8 nC at 10 V gate drive, with input capacitance of 408 pF at 25 V drain bias. That low Qg means a modest gate driver can switch it fast — a 1 A driver charges the gate in under 10 ns, so the switching losses stay low even at a few hundred kHz. The ±20 V maximum gate-to-source rating gives headroom for gate-drive transients on a 12 V or 15 V rail.
The 2.4 W power dissipation at case temperature is the thermal budget — the PowerFlat's exposed pad needs a good copper area on the PCB to keep the junction below 150°C at full drain current.
