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.
