3. T he 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.

T he specified limits are for IZ(AC) = 0.1 IZ(dc) with the AC frequency = 1 KHz.
