Follow up question - If in the future I use a smaller transformer will the diode 1.5KE36Ca work or will I have to get the 1.5KE33Ca?

It isn't so much the "size" of the transformer as much as it is the maximum operating voltage of the transformer.

In general, for up to about 24VAC, the 1.5KE36Ca is a good universal catch all solution.

Some operators get very pedantic and because their power supplies only push 18VAC maximum, they decide to go with the 1.5KE33Ca even though a 1.5KE36Ca would be perfectly acceptable for 18VAC as well.
