    Hi,

    I want to pulse 9volts 200 times per second controlled by a 5 volt signal.

    What would be the best mosfet for me?

    Thanks

    Hello,

    When you are switching with a 5 Volts gate voltage, you should look for a logic gate mosfet.
    How much current needs to be switched by the fet on the 9 volts side?
