Notes :
(1) The type numbers shown have a standard tolerance of ± 5% on the nomainal Zener voltag.
(2) Nominal Zener voltage is measured with the device junction in thermal equilibrium at TL= 30°C ±1°C
(3) ZZT and ZZK are measured by divice drop across the device by the AC current applice.
The specified limits are for IZ(AC) = 0.1 IZ(DC) with the AC frequency 1 KHz
