hi.
Igniters need around 2A to burst. I tought this FET would be good because my battery is 12V today, but can be larger maybe later.
Plus, if the igniter don't burst (because it happen sometimes), i will have a short during 10 or 20 ms, i really don't know the total current the battery will give in case of a short, maybe a lot. I use a 12V 1800 mAh battery. So this FET can handle 27A, i think this is a good way to "self" protect the FET am i wrong ?
