FIGURE 1 DESIGN DATA CASE: DO-213AA, Hermetically sealed glass case. (MELF, SOD-80, LL34) LEAD FINISH: Tin / Lead POLARITY: Diode to be operated with the banded (cathode) end positive. MOUNTING POSITION: Any. MOUNTING SURFACE SELECTION: The Axial Coefficient of Expansion (COE) Of this Device is Approximately +6PPM/C. The COE of the Mounting Surface System Should Be Selected To Provide A Suitable Match With This Device. NOTE 1 NOTE 2 NOTE 3 Zener impedance is derived by superimposing on lZT A 60Hz rms a.c. current equal to 10% of lZT. The maximum allowable change observed over the entire temperature range, per JEDEC standard No.5. Zener voltage range equals 12.8 volts + 5%. 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 CDLL4896 1000 500 ZENER IMPEDANCE ZZT (OHMS) 200 100 50 20 10 5 2 1 thru CDLL4915A 2 4 6 8 10 12 OPERATING CURRENT lZT (mA) FIGURE 2 ZENER IMPEDANCE VS.
