Suffix "A" equals + 10 %. "C" suffix=. 2 % and "D" suffix= + 1 %.No Suffix equals + 20 %. Zener voltage is read using a pulse measurement, 10 milliseconds maximum. NOTE 2 Zener impedance is derived by superimposing on lZT a 60Hz rms ac current equal to 10 % of IZT. NOTE 3 VZ is the maximum difference between VZ-@ IZT and VZ at IZL measured with the device junction in thermal equilibnum at an ambient temperature of +25 + 3C. 1 Revision Date: 12/13/2011 New Product CD5518B thru CD5546B 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.
