This transistor is very non-critical here.
The only important parameters of the transistor in this application is that it needs to be a P-channel type, and have a Drain Source breakdown rating of at least 160V. Many MOSFETs have 60V or 100V ratings and this is not enough. The current handling capability and power dissipation capability are of no consequence. It only passes microamps and dissipates microwatts.
I chose this device just because it met the criteria (P type, high voltage) and was easily available and cheap. The large package and power handling are not a requirement. Only the P type and high voltage.
