Web4 okt. 2011 · To reach 90% of the final gate voltage, for example, takes 2.3 time constants. When the FET actually "switches" is more tricky. The FET won't suddenly go from full off to full on at a particular gate voltage, but there is a gate voltage at which a small incremental change will make the most difference in the FET output characteristic.
