VF=1.5V max. @ IF=200mA TOLERANCE DESIGNATION Standard tolerance on nominal ZENER voltage is ±5%, ZENER IMPEDANCE I ( ac rms ) = 10% Izt ZENER KNEE IMPEDANCE I (ac rms ) = 10% Izk MAXIMUM ZENER CURRENT The nominal Izm currents shown are applicable for devices having regulator voltages approximately 10% above the nominal Vz values shown. These values do not represent absolute limits. The actual steady state current-voltage product must not exceed the power rating. www.slkormicro.com 2
