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:...
