Nominal Zener voltage is measured with the device junction in thermal equilibrium at an ambient temperature of 25°C + 3°C. "C" suffix denotes a + 2% tolerance and "D" suffix denotes a + 1% tolerance. Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal to 10% of IZT. FIGURE 1 DESIGN DATA CASE: DO-213AA, Hermetically sealed glass case. (MELF, SOD-80, LL34) THERMAL IMPEDANCE: (ZJX): 35 °C/W maximum POLARITY: Diode to be operated with the banded (cathode) end positive. 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 123 CDLL4614 thru CDLL4627 FIGURE 2 Pd, Rated Power Dissipation (mW) 500 400 300 200 100 0 0 25 50 75 100 125 150 175 TEC , End cap temperature (°C) POWER DERATING CURVE 1000 500 400 300 3.3 VOLT ZENER IMPEDANCE ZZT (OHMS) 200 100 5.1 VOLT 50 40 30 20 10 5 4 6.2 VOLT 3 2 1 .1 .2 .5 1 2 5 10 20 50 100 OPERATING CURRENT IZT (mA) FIGURE 3 ZENER IMPEDANCE VS.
