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 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.
