	NOTE 1			Zener voltage range equals nominal voltage +																	5% for “B” Suffix. “A” Suffix denotes +											10%,
				No Suffix denotes +									20%. "C" suffix = +					2% and "D" suffix = +							1%.
	NOTE 2			Zener voltage is read using a pulse measurement, 10 milliseconds maximum.
	NOTE 3			Zener impedance is derived by superimposing on 1																	ZT A 60Hz rms a.c. current equal
				to 10% of 1				ZT
