250 V P-channel in a SOT-223 — the high-side switch for compact supplies
It is designed for high-side switching in applications where a positive supply rail must be switched on and off without a level-shifted gate drive — a P-channel simplifies the drive circuit because the source connects to the rail and the gate is pulled low to turn on.
On-resistance and gate drive — 12 Ohm at 10 V, but also specified at 2.8 V
Gate charge is 5.4 nC at 10 V, so switching losses at moderate frequencies (tens of kHz) are low.
Maximum power dissipation is 1.8 W at 25°C ambient, which in a SOT-223 package means the PCB copper area under the tab is the primary heatsink.
Active lifecycle — no end-of-life watch needed
It is ROHS3 compliant.
