I am using UC 1708 driver (with capability 3A) at 15V to switch 2N6766 power mosfet (frequency 100kHz). Gate series resistor is 10E. There is a zener diode 1N759 and 4.7 k between gate and source of the mosfet . The gate transient current peak is 350 mA. What is limiting the gate current to 350mA, when 1708 can supply 3A?
 

Mainly driver slew rate + gate capacitance, also the series resistance sets an absolute limit to the gate current.
