Hello all
I have always tested zeners with a DC source and a simple series resistor-substitution box. No problem.
I am now checking some old 1N746A zeners (3.3v,½w) and they are not regulating at all; just acting like a resistor.
Are they all defective? Is there a better way? Should I be doing something different?
Thanks
Marty
