TOLERANCE AND TYPE NUMBER DESIGNATION (V Z) The type numbers listed have a standard tolerance on the nominal zener voltage of ± 5%. 2. SPECIALS AVAILABLE INCLUDE N ominal zener voltages between the voltages shown and tighter voltage, for detailed information on price, availability and delivery, c ontact you nearest Tak Cheong representative. 3. ZENER VOLTAGE (V Z) MEASUREMENT The zener voltage (V Z) is tested under pulse condition. The measured V Z is guaranteed to be within specification with device junction in thermal equilibrium. 4.
