tolerance. note 2: zener voltage (vz) is measured at t l = 25 o c (+8, -2 o c). voltage measurement to be performed 40 10 milliseconds after application of dc current. note 3: the zener impedance is derived from 1 khz ac voltage result ing from an ac current modulation having an rms value equal to 10% of the dc zener current (i zt or i zk ) superimposed on i zt or i zk . see micro note 202 for zener impedance variation with different operating currents. note 4: the maximum current (i zm ) shown is for a 5% tolerance devices. the i zm for other tolerances can be calculated using the formula: i zm = p/v zm where v zm is the v z at the high end of the voltage toleranc e specified and p is the rated power for the method of mounting. note 5: the surge current (i zsm ) is specified as the maximum peak of a non-re current half-sine wave of 8.3 ms duration. note 6: voltage regulation (v z ) is the difference between the volt age measured at 10% and 50% of i zm .
