TOLERANCES: ALL Dimensions + 2 mils, Except Anode Pad Where Tolerance is + 0.1 mils. NOTE 1 Suffix "B" voltage range equals nominal Zener voltage + 5%. Suffix "A" equals + 10%. No Suffix equals + 20%. 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 a.c. current equal to 10% of lZT. NOTE 3 VZ is the maximum difference between VZ @ 1ZT and VZ at 1ZL measured with the device junction in thermal equilibrium at an ambient temperature of +25 + 3C. 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 CD5518B thru CD5546B 1000 500 400 300 200 ZENER IMPEDANCE ZZT (OHMS) 3. 3 VO LT 27 100 VO LT 1 5.
