2. TOLERANCE AND TYPE NUMBER DESIGNATION The type numbers listed indicate a tolerance of 5%.
3. ZENER VOLTAGE (V_Z) MEASUREMENT
Nominal Zener voltage is measured with the device junction in thermal equilibrium with ambient temperature at 25C.
4. ZENER IMPEDANCE (Z_Z) DERIVATION Z_ZT and Z_ZK are measured by dividing the ac voltage drop across the device by the ac current
applied. The specified limits are for I_Z(ac) = 0.1 I_Z(dc) with the ac frequency = 60 Hz.
*Include SZ-prefix devices where applicable.
