													CIRCUIT LAYOUT DATA:
													Backside must be electrically
													isolated.
													Backside is not cathode.
	NOTE 1	Zener impedance is derived by superimposing on l						ZT	A 60Hz rms a.c.				For Zener operation cathode must
		current equal to 10% of l			ZT.								be operated positive with respect
													to anode.
	NOTE 2	The maximum allowable change observed over the entire temperature
		range i.e.,the diode voltage will not exceed the specified mV at any											TOLERANCES:					ALL
		discrete temperature between the established limits, per JEDEC
													Dimensions +					2 mils
