TOLERANCES: ALL Dimensions + 2 mils NOTE 1 Zener voltage range equals nominal Zener voltage + 5% for no suffix types. Zener voltage is read using a pulse measurement, 10 milliseconds maximum. "C" suffix = + 2% tolerance and "D" suffix = + 1% tolerance. NOTE 2 Zener impedance is derived by superimposing on lZT A 60Hz rms a.c. current equal to 10% of lZT. 22 COREY STREET, MELROSE, MASSACHUSETTS 02176 PHONE (781) 665-1071 FAX (781) 665-7379 WEBSITE: http://www.cdi-diodes.com E-mail: mail@cdi-diodes.com CD4614 thru CD4627 1000 500 400 300 200 ZENER IMPEDANCE ZZT (OHMS) 100 50 40 30 20 10 5 4 3 2 1 .1 .2 .5 1 2 5 10 20 50 100 OPERATING CURRENT IZT (mA) 3.3 VOLT 5.1 VOLT 6.2 VOLT FIGURE 3 ZENER IMPEDANCE VS.
