(MELF, LL41) LEAD FINISH: Tin / Lead THERMAL RESISTANCE: (ROJEC): 50 °C/W maximum at L = 0 inch THERMAL IMPEDANCE: (ZOJX): 15 °C/W maximum POLARITY: Diode to be operated with the banded (cathode) end positive. MOUNTING POSITION: Any. NOTE 1 No suffix = + 10% tolerance on nominal Zener voltage, suffix “A” signifies +5%, "C" suffix signifies + 2% and "D" suffix signifies + 1%. NOTE 2 Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal to 10% of 1ZT. NOTE 3 Zener voltage is measured with the device junction in thermal equilibrium at an ambient temperature of 25°C + 3°C. 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 109 1N3821AUR-1 thru 1N3828AUR-1 and CDLL3821A thru CDLL3828A Pd, Rated Power Dissipation (mW) FIGURE 2 1000 800 600 400 200 0 0 25 50 75 100 125 150 TEC , End cap temperature (°C) POWER DERATING CURVE ZZT, Zener Impedance (OHMS) 1000 100 10 1 .1 1.0 10 OPERATING CURRENT lZT (mA) FIGURE 3 ZENER IMPEDANCE VS.
