TOLERANCES: ALL Dimensions + 2 mils NOTE 1 NOTE 2 NOTE 3 Zener voltage range equals nominal voltage +5% for "A" Suffix types. No Suffix denotes + 10%. "C" suffix = + 2% and "D" suffix = + 1%. Zener voltage is read using a pulse measurement, 10 milliseconds maximum. Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal to 10% of 1ZT. 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 15 MILS 23 MILS CD746A thru CD759A CD4370A and thru CD4372A 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.
