The zener voltage (VZ) is tested under pulse condition of 1mS. The device numCers listed have a standard tolerance on the nominal zener voltage of ±2%. 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. http://www.yeashin.com 2 REV.02 20140509 DEVICE CHARACTERISTICS MMSZ52xxA Fig.2 EFFECT OF ZENER VOLTAGE ON ZENER IMPEDANCE Fig.1 TYPICAL FORWARD VOLTAGE POWER PASSIPATION,mW 600 500 400 300 200 100 0 0 25 50 75 100 125 150 175 200 TEMPERATURE [℃ ] Fig.3 POWER DISSIPATION VS.
