The more I look at the AliExpress picture the more confused I am. If this is actually an N-channel IPT015N10N5 MOSFET why is it shown here as a high side switch? The Drain is labelled Out(+) and the Source is labelled In(+)! In that case wouldn't it simply conduct via the MOSFET body diode? What am I missing here? My electronics knowledge is limited at best.
EDIT: I was expecting the usual AliExpress shenanigans but I realized that if U1 is able to drive the gate higher than the source voltage the NPN can be driven as a high side switch. That makes these a pretty good deal given that it's a $10 MOSFET!
