ZVN4206A N-Channel MOSFET

December 24, 2010 Paul Gardiner Theory Leave a comment

In the MOSFET, the gate is isolated from the conducting channel by a thin insulating layer (as indicated by the symbol). This forms a capacitor which can be used as the timing capacitance. As with all capacitors, the gate capacitance also has a leakage current. For the ZVN4206A the gate capacitance is typically 300pF and the leakage current 1nA. The […]
