4. The type numbers shown have a standard tolerance of ±5% on the nominal Zener voltage. 5. Nominal Zener voltage is measured with the device junction in thermal equilibrium at TL = 30°C $1°C. 6. 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. *The “G’’ suffix indicates Pb−Free package available. See Ordering Information.
