I am trying test my p-channel mosfet (IRF9Z34) high side switch on load. On circuit simulator I get the result I expect, Rdson (VM1) is low and load current is 1.4A. (In the target system the gate will be controlled, here the mosfet is always on for tests). T1 - P-MOSFET IRF9Z34.
In the real circuit current is max 0.9A, so I have very big Rdson, I don't understand why. Vgs > Vth, The power supply has a current effiency > 2A.
