(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. NOTE 2 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. 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. 6 LAKE STREET, LAWRENCE, MASSACHUSETTS 01841 PHONE (978) 620-2600 FAX (978) 689-0803 WEBSITE: http://www.microsemi.com 107 600 500 Pd, Rated Power Dissipation (mW) CDLL3154 thru CDLL3157A 400 300 200 100 0 0 25 50 75 100 125 150 TA, Ambient Temperature (°C) FIGURE 2 POWER DERATING CURVE ZENER IMPEDANCE ZZT (OHMS) 100 50 10 5 1 8 9 10 11 12 13 OPERATING CURRENT lZT (mA) FIGURE 3 ZENER IMPEDANCE VS.
