For currents above 1A where high-side control is required in order to use stock harness we have VND5E025AK, a thermally protected P-MOSFET, called a High Side Switch (HSS) by ST.
1) pin#1 mark for PowerSSO-24 chip
2) Larger diameter holes for GND, VCC and out wire holes. Larger diameter holes for input wires also, just in case
3) larger diameter heatsink vias to simplify soldering
