250 V P-Channel MOSFET in a SOT89 — what it is for
Packaged in a PG-SOT89 surface-mount case, it is built for medium-voltage switching and load management in space-constrained designs. The 12 Ohm maximum on-resistance at 190 mA and 10 V gate drive keeps conduction losses predictable for low-current high-voltage rails.
Where it fits in a design
This is a high-voltage P-Channel switch for load disconnect, reverse-polarity protection, and high-side switching in power supplies, battery management, and industrial controls. The SOT89 footprint is small enough for handheld and portable equipment but still hand-solderable for prototyping.
