The type numbers listed have zener voltage as shown and have a standard tolerance on the nominal zener voltage of ±5% in Blue marking, suffix A=±10% in Brown marking, C= ±2% in Orange marking and D = ±1% in Yellow marking. 2. For detailed information on price, availability and delivery of nominal zener voltages between the voltages shown and tighte r voltage tolerances, contact your nearest Tak Cheong Electronics representative. 3. 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 to IZT or IZK.
