Thanks Claire, good video.
Another question, the reverse voltage protection is to -30V. Is there any leeway in the MOSFETs specifications with this, in that could it potentially be a little higher for very breif periods and still not conduct?
I have an automotive circuit with TVS diodes that are 'transparent' to the circuit at 24V (for example during 24V jump starting etc.), but they clamp at +/-32V (the lowest I can get it). The MOSFET will protect the circuit up to -30V during negative voltages, but if there is a >-30V transient then the circuit will be exposed to some negative voltage, as the TVS won't clamp until -32V.
If the MOSFET can not stop any breif negative transients as low as -32V, is it possible for me to remove the MOSFET and solder in a replacement, or could that potentially affect other things on the board. If so I may need to implement another MOSFET externally.
