How do I pick a suitable SMD mosfet to control a 24V pneumatic valve with PIC32?
If you're looking for the power required you missed it.



Solenoid coil specifications from page 2 of the datasheet. (Click for high-resolution.)

The worst case is 15 W on the DC versions so allow for \$ I = \frac P V = \frac {24}{15} \ \text A \$.

Go for a MOSFET that is rated at > 1 A and can be turned fully on by a logic-level output from your PIC32 - 3.3 V or 5 V, as required.
