    Hi All,
    I want to make a time delay circuit using transistors,
    12v supply switch on a 3Watt bulb and go off after about 3 seconds
    if possible, I don't want to use a relay or 555
    and I would like to use pnp ZTX 751 transistors which I have plenty of !
  2. Peter, since I recently posted something close to what you want, I'd
    like to save time and suggest that you might try something like the
    I haven't looked at the data sheet for the Zetex part, though. I'm
    assuming that you already know it can handle the 3W load.
