There is a well-known reverse polarity protection technique using a P-channel MOSFET like so:
If I use the common BSS84 for this task, it can only handle 130mA continuous current through it. Lets say I want to use the BSS84 to reduce the number of unique parts on my board, but I need to support 200mA continuous current. The battery voltage could be anything from 2.5 to 4.5V. Is there any significant concern with doing the following to retain the circuit protection properties, and increase the current support?
