There are two types of MOSFET and they are named: N-type or P-type. You don't need to know the pin out of the device you're testing. SEE Test Method and Guidelines: 2014. For P-channel devices, use the same procedure, but with reversed polarities. The objective of this procedure will be to determine as much information as possible about an "unknown" MOSFET, using only simple DMM measurements.
