																													CIRCUIT LAYOUT DATA:
																													For Zener operation, cathode
																													must be operated positive with
	NOTE	1			Zener voltage range equals nominal voltage +												5% for “A” Suffix No Suffix denotes +							10%.
	NOTE	2			"C" suffix denotes +				2%, "D" suffix denotes +							1%.													respect to anode.
					Zener voltage is read using a pulse measurement, 10 milliseconds maximum.
	NOTE 3																												TOLERANCES:				ALL
					Zener impedance is derived by superimposing on 1												ZT	A 60Hz rms a.c. current equal											Dimensions +			2 mils
					to 10% of 1		ZT .
