TOLERANCE AND TYPE NUMBER DESIGNATION (VZ) The type numbers listed have a standard tolerance on the nominal zener voltage of ± 5%. Device tolerance of ±2% is indicated by a “C” instead of an “A”. 2. SPECIALS AVAILABLE INCLUDE Nominal zener voltages between the voltages shown and tighter voltage, for detailed information on price, availability and delivery, contact you nearest Tak Cheong representative. 3. ZENER VOLTAGE (VZ) MEASUREMENT The zener voltage (VZ) is tested under pulse condition. 4. ZENER IMPEDANCE (ZZ) DERIVATION The zener impedance is derived from the 60 cycle AC voltage, which results when an AC current having an RMS value equal to 10% of the DC zener current (IZT or IZK) is superimposed on IZT or IZK.
