(MELF, SOD-80, LL34) LEAD FINISH: Tin / Lead POLARITY: Diode to be operated with the banded (cathode) end positive. MOUNTING POSITION: Any. NOTE 1 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 i.e., the diode voltage will not exceed the specified mV at any discrete temperature between the established limits, per JEDEC standard No.5. NOTE 2 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. 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 Pd, Rated Power Dissipation (mW) CDLL3154 thru 600 500 400 300 200 100 0 0 25 50 75 100 125 150 175 CDLL3157A TA, Ambient Temperature (C) FIGURE 2 POWER DERATING CURVE 100 ZENER IMPEDANCE ZZT (OHMS) 50 10 5 1 8 9 10 11 12 13 OPERATING CURRENT lZT (mA) FIGURE 3 ZENER IMPEDANCE VS.
