    Mosfet switching noise from pcb

    if a mosfet drain is switching 200hz-800khz at 400v 8-9 amps pulsed (1.5amps average) and is soldered right onto a large drain copper pour >20mm^2 will it emanate a lot of emi and even damage onboard components?

    800kHz is a lot, its close to a megahertz. The load type also matters.You have to apply the proper techniques and change the PCB layout.
