Tolerance and T ype Number Designation. The type numbers listed have a standard tolerance on the nominal zener voltage of ±5%. 2. Specials Available Include: A. Nominal zener voltages between the voltages shown and tighter voltage tolerances. B. Matched sets. 3. Zener V oltage (V Z ) Measurement. Guarantees the zener voltage when measured at 90 seconds while maintaining the lead temperature (T L) at 30 O C, from the diode body . 4. 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 . equal to 10% of the dc zener 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 Page2 Surface Mount Zener Diodes CZRW5221B-G thru CZRW5259B-G 8 100 TEMPERATURE COEFFICIENT,mV/ o C) TEMPERATURE COEFFICIENT,mV/ o C) 7 6 5 4 3 2 1 0 -1 -2 -3 2 3 4 5 6 7 8 9 10 11 10 1 10 12 100 NOMINAL ZENER VOLTAGE, Volts TYPICAL REVERSE NOMINAL ZENER VOLTAGE, Volts CURRENT STEAD Y S TAT E POWER 1000 DERA TING 1000 IZ = 1 mA FORWARD CURRENT, mA DYNAMIC IMPEDANCE, O TJ=25 C IZ(AC)=0.1IZ(DC) F=1 kHZ 100 5 mA 20 mA 10 100 O 150 C 10 75OC O 25 C 1 1 10 1 0.4 100 0.5 0.6 0.8 0.9 1.0 1.1 1.2 FORWARD VOLTAGE, Volts NORMAL ZENER VOLTAGE, Volts TYPICAL FORW ARD VOL TAGE 1000 1.2 0.8 0.6 PD V.S.
