TOLERANCE AND VOLTAGE DESIGNATION The type numbers listed have zener voltage as shown and have a standard tolerance on the nominal zener voltage of ±5%. Device of ±2% is indicated by a “C” instead of a “B” 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. The measured VZ is guaranteed to be within specification with device junction in thermal equilibrium. 4. ZENER IMPEDANCE (ZZ) DERIVATION Zener impedance is derived from the 60-cycle ac voltage, which results when an ac current having an RMS value equal to 10% of t he dc zener current (IZT) is superimposed to IZT .
