Electrical Specifications @ +25 ºC (Unless Otherwise Specified)
NOTE 1 Zener impedance is derived by superimposing on l ZT a 60 Hz rms ac current equal to 10% of l ZT.
NOTE 2 The maximum allowable change observed over the entire temperature range i.e.,the diode voltage will not
exceed the specialized mV at any discrete temperature between the established limits, per JEDEC standard No.5.
