Zener Impedance (Z Z ) Derivation. The zener impedance is derived from the 60 cycle ac voltage, which results when an AC current having an rms value current (I ZT or I ZK ) is superimposed on I ZT or IZK . 5. Surge Current (I R ) Non-Repetitive. The rating listed in the electrical characteristics table is maximum peak, non-repetitive, reverse surge current of 1/2 square wave or equivalent sine wave pulse of 1/120 second duration superimposed on the test current, I ZT , per JEDEC registration; however, actual device capability is as described in Figure 5. “-G” suffix designated RoHS compliant version www.comchiptech.com P age2 Surface Mount Zener Diodes CZRW5221B-G thru CZRW5259B-G 8 7 100 TEMPERATURE COEFFICIENT,mV/ o C) 6 5 4 3 2 1 TEMPERATURE COEFFICIENT,mV/ o C) 3 4 5 6 7 8 9 10 11 12 10 0 -1 -2 -3 2 1 10 100 NOMINAL ZENER VOLTAGE, Volts NOMINAL ZENER VOLTAGE, Volts TYPICAL REVERSE CURRENT STEAD Y S TAT E POWER DERA TING 1000 FORWARD CURRENT, mA 1000 TJ=25 C IZ(AC)=0.1IZ(DC) F=1 kHZ O DYNAMIC IMPEDANCE, IZ = 1 mA 100 5 mA 20 mA 100 10 10 150 C 75OC O 25 C O 5C O 1 1 10 NORMAL ZENER VOLTAGE, Volts 100 1 0.4 0.5 0.6 0.7 0.8 0.9 1.0 1.1 1.2 FORWARD VOLTAGE, Volts TYPICAL FORW ARD VOL TAGE 1.2 1.0 0.8 0.6 1000 0 V BIAS 1 V BIAS 100 BIAS AT 50% OF VZ NOM 10 TA=25oC POWER DISSIPATION, Watts PD V.S.
