The type numbers shown have a standard tolerance of ±5% on the nominal Zener voltage. 4. Nominal Zener voltage is measured with the device junction in thermal equilibrium at T L = 30°C ± 1°C. 5. ZZT and ZZK are measured by dividing the AC voltage drop across the device by the ac current applied. The specified limits are for IZ(AC) = 0.1 IZ(dc) with the AC frequency = 1 KHz.
