A bit more details: The difference between a P and an N is that an N-channel fet will turn on (aka, conduct) when a voltage greater than the drain&source voltages is applied to the gate, while a P-channel fet will turn on when a voltage less than the drain&source voltage is applied to the gate. IRF MOSFET Power Transistors, Mosfet Transistors, IRF Mosfet Transistor. (For the p-channel JFET, the n-type layer will be doped higher than the p-channel) h. Also, I think the 10 kOhm pull-up is a bit weak. Encompassing N- and P-channels, the MOSFET Master Table portfolio ranges from 8V to 650V packaged in single, dual and complementary configurations.
