The picture is a Wall charging over-voltage protection component:
This is a typical component in mobile phone.
I have some questions for that:
(1). Why use NMOS? Just because the package of NMOS is smaller than PMOS?
(2). Why use two NMOS?
Thanks for the comments.

S1 is directly linked to S2.
G1 is directly linked to G2, and both are controlled by external signal.
D1 is current input, and D2 is output.
