TOLERANCE AND VOLTAGE DESIGNATION The type numbers listed have zener voltage as shown and have a standard tolerance on the nominal zene r voltage of ±5%. Suffix (BLANK) = ±10%, Suffix C = ±2% and D = ±1%. 2. SPECIALS AVAILABLE INCLUDE Nominal zener voltages between the voltages shown and tigh t er voltage, for detailed information on price, availability and delivery, contact you nearest Tak Cheong representative. 3. ZENER VOLTAGE (VZ) MEASUREMENT The zener voltage (V Z) is tested under pulse condition. 4. ZENER IMPEDANCE (Z Z) DERIVATION Z ener 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) is su perimposed to IZT .
