2. TOLERANCE AND TYPE NUMBER DESIGNATION The type numbers listed indicate a tolerance of 5%.
3. ZENER VOLTAGE (VZ) MEASUREMENT
Nominal Zener voltage is measured with the device junction in thermal equilibrium with ambient temperature at 25C.
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.
