No Suffix denotes + 10 %. Zener voltage is read using a pulse measurement, 10 milliseconds maximum. "C" suffix = + 2% and "D" suffix = + 1%. NOTE 2 Zener impedance is derived by superimposing on lZT a 60Hz rms ac current equal to 10 % of IZT. 1 Revision Date: 2/17/2012 New Product CD4728A thru CD4764A Outline Drawing DESIGN DATA Anode METALLIZATION: Top: Back: (Anode) Al (Cathode) Au AL THICKNESS: 25,000 A Minimum GOLD THICKNESS: 4,000 A Minimum CHIP THICKNESS: 10 Mils CIRCUIT LAYOUT DATA: For Zener operation, cathode must be operated positive with respect to anode.
