The Zener Voltage (VZ) is tested under pulse condition of 10mS. The device numbers listed have a standard tolerance on the nominal zener voltage of ±2%. For detailed information on price, availability and delivery of nominal zener voltages between the voltages shown and tighter voltage tolerances, contact your nearest Tak Cheong Electronics representative. 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. www.shunyegroup.com.cn Fig.2 EFFECT OF ZENER VOLTAGE ON ZENER IMPEDANCE Fig.1 TYPICAL FORWARD VOLTAGE Fig.3 MAXIMUM NONREPETITIVE SURGE Fig.5 ZENER BREAKDOWN CHARACTERISTICS Fig.4 TYPICAL CAPACITANCE Fig.6 ZENER BREAKDOWN CHARACTERISTICS Fig.7 TYPICAL LEAKGE CURRENT www.shunyegroup.com.cn
