I made a mistake when I designed my PCB and a lot of P-MOSFET are placed with wrong orientation:
As you can see, I inverted the drain/source and in this way Q1 is actually by-passed by the built-in DS diode. The package of BSS-84 is SOT-23.
Because I have dozens of these MOSFET in my PCBs I'm looking for a solution to save the prototypes.
I searched for a P-MOSFET with inverted D-S but I find nothing suitable. Any idea?
