Thank you for your reply.
I have already checked the Vishay FET.
This FET has a very large Vgs(20V) and Vds(30V).
If VBUS is fixed at 5V, I think it is not necessary large Vgs/Vds.
Is it correct?
FET with Vgs(Vth) in -1V to -2.2V range with Id rating based on your application (5A maximum under USB-PD spec) can be selected for the application.
Since VBUS voltage is fixed at 5V, Vds value greater than 5V with the above Vgs(Vth) and Id parameters can be used.
Thank you for your support.
I understood all things.
