Op amps with either input grounded have a fixed input capacitance parameter, CI, and this device has a 2500pF @ 50V maximal input capacitance.To operate this transistor, you will need a 100V drain to source voltage (Vdss).A device like this reduces its overall power consumption when it uses drive voltage (4.5V 10V).
