Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
3. Zener voltage is measured with the device junction in thermal equilibrium with an ambient temperature of 25°C.
4. Zener Impedance 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.
