NOTE 1 - TOLERANCE AND VOLTAGE DESIGNATION
The JEOEC type numbers shown are :t 10% with guaranteed limits for VZ, )R, and VF. Units with guaranteed limits for an six parameters are indiceted by a "8" suffix for :t 5.O"k units, "C" suffix for :t 2.0% and "0" suffix for :t 1.0%.
NOTE 2 - ZENER VOLTAGE (Vzl MEASUREMENT
Nominal zener voltage is measured with the device junction in thermal equilibrium with ambient temperature of 250 C.
NOTE 3 - ZENER IMPEDANCE (Zzl DERIVATION
The zener impedance is derived from the 60 Hz ac voltage, which results when an ae current having an rms value equal to 10% of the de zener current IIZT) is superimposed on 'ZT.
NOTE 4 - REVERSE LEAKAGE CURRENT URI
Reverse leakage currents are.
