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.
