  1. Hi

    I'm in need of a 18 Volt 5 Watt Zener diode, I have only 18 Volt 1 Watt
    Zener diodes.
    My question is, can I put 5 one Watt Zener diodes parallel to make it 5 Watt
    ?

    Thank you in advance
    Gerhard.
     
  2. Or the OP could put half a dozen 3v 1W zeners in *series* to produce the
    desired voltage.

    Or use a three terminal regulator eg LM7818.

    etc..
