ZENER DIODE COLOR CODES
Most manufacturers stamp the ID right on the diode but some do use color
banding as the method of identification. For purposes of alignment, the side
with any color band closest to either side of the diode is the equivalent of
the left side of this table. The three examples in the table when associated
with the values in the lower table are identified as 1N64E for the top diode,
1N452G for the middle diode and 1N4762 for the bottom diode.
