or admin if you ever try this?

I have found some material on net but it create problem in Proteus simulation.

I found this circuit diag! on other fourm:



here is one confusion abt diodes. take a look at MCT2E part, there are 2 zener diode and one simple diode symbol.

along simple diode there is written 4148 thats zener diode :O and along zener diode diag's there is noting written series.

so can anyone clear this confusion.

thanks,
M.S.
