A StripFET is essentially a trench FET, they can suffer a form of thermal runaway when used in analogue mode.I was thinking that with RDS(on) the resistor of the MOFFET is max 0.014 Ohm, with a current clamp around 14A: P =R x I^2= 0.014*(14^2) = 2.75W that is 40 times less of the Total dissipation at TC = 25°C =110 W (from datasheet) it should not give enough heat to damage the PCB. Is my thinking wrong?
