Hi,
I have a STP12PF06. (P channel)
Drain is connected to 5.25v,
load (~0.02A) is connected source to 0v
Datasheet claims gate threshold voltage 2-4v.
I was under the impression connecting the gate to 0v would give my load the full voltage while connecting gate to 5.25 supply would give ~0v at the source.
Connecting Gate to the 5.25v supply actually gives a voltage at the source pin of 4.87v.
I havent used mosfets before but i thought this would work. Am i misinterpreting something here?
Thanks.
