N-ch, 55v, 47a
• IRF mosfets need 10V at the gate to fully turn on.
  IRL mosfets need 5V at the gate to fully turn on.

• A MOSFET is like a variable resistor. The Gate-Source voltage controls the Drain-Source Resistance.
  When there is no voltage between the Gate-Source , the Drain-Source resistance is very high, effectively an open circuit.
• N-channel: The Source is connected to ground. To turn it on, apply a voltage to the Gate. To turn it off, ground the Gate.
• P-Channel: The Source is connected to Vcc. To turn it on, connect the Gate to ground. To turn it off, connect the Gate to Vcc.
