MOUNTING POSITION: Any. NOTE 1 No suffix = + 10% tolerance on nominal Zener voltage, suffix A signifies +5%, suffix signifies + 2% and suffix signifies + 1%. MOUNTING SURFACE SELECTION: The Axial Coefficient of Expansion (COE) NOTE 2 Zener impedance is derived by superimposing on 1 A 60Hz rms a.c. current equal to ZT 10% of 1 Of this Device is Approximately ZT. +6PPM/C. The COE of the Mounting NOTE 3 Zener voltage is measured with the device junction in thermal equilibrium at an ambient temperature of 25C + 3C. 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: 1N3821AUR-1 thru 1N3828AUR-1 and CDLL3821A thru CDLL3828A FIGURE 2 1000 800 600 400 200 0 0 25 50 75 100 125 150 175 T , End cap temperature (C) EC POWER DERATING CURVE 1000 100 10 1 .1 1.0 10 100 OPERATING CURRENT l (mA) ZT FIGURE 3 ZENER IMPEDANCE VS.
