Nominal Zener voltage is measured with the device junction in thermal equilibrium with ambient temperature at 25 ° C. 

4. **ZENER IMPEDANCE (ZZ) DERIVATION** 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 = 60 Hz. 

*Include SZ-prefix devices where applicable.
