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.
