Hi, does anyone know under what kind of condition will a MOSFET give a large source current for a very short moment and then return to its quiescent current value? (By the way, the MOSFET is operating in linear or triode region, not saturation region)
So far, the only thing I can think of is a sudden increase in the gate to source, Vgs. Any other answers??

Give us an idea of the width and current of the pulse and the quiescent current. And the Vds for quiescent and pulse. oh.. and type of the MOSFET would be useful.
