    Hello,

    I have PIC12F629 and want with I/O port drive IRFP450. I attached wiring diagram.
    With IRFP450 I want to drive 230V~ regular bulb 100W. Can I drive IRFP450 directly?

    Is my wiring diagram OK?

    thanks

    If that's 230V *AC*, then I think you need to first read the AAC ebooks before you start designing this circuit. ;)

    Even if it's DC, you'll be better off using a driver (discrete or chip) for the MOSFET, if for no other reason than so a failure doesn't pop your PIC.

    Welcome, El da.

    I have moved your posts to their own thread. We refer to posting in an existing thread hijacking, and ask that you not do it. Especially when the old thread is very old - http://forum.allaboutcircuits.com/showthread.php?t=8270&page=3

    You can't use a FET to control AC. Look at the data sheet and see the inherent diode in the FET structure. It is better to use a TRIAC to control AC.
