Units Z R F C/W maximum with A suffix are +10% with guaranteed limits for V , l , and V . Units with guaranteed limits for Z R F all six parameters are indicated by a B suffix for +5.0% units, C suffix for +2.0% and D suffix for +1.0%. POLARITY: Diode to be operated with the banded (cathode) end positive. NOTE 2 Zener voltage is measured with the device junction in thermal equilibrium at an ambient temperature of 25C + 3C. MOUNTING POSITION: Any. NOTE 3 Zener impedance is derived by superimposing on 1 A 60Hz rms a.c. current equal to 10% of 1 ZT ZT. NOTE 4 Reverse leakage currents are measured at V as shown on the table. R NOTE 5 VZ is the maximum difference between VZ at lZT and V at l measured with Z ZL the device junction in thermal equilibrium at the ambient temperature of +25C +3C. 6 LAKE STREET, LAWRENCE, MASSACHUSETTS 01841 PHONE (978) 620-2600 FAX (978) 689-0803 WEBSITE: 1N5518 thru 1N5546D INCLUDING -1 VERSIONS 400 300 200 100 0 0.2 0.4 0.6 0.8 1.0 L, lead Length to Heat Sink (inches) FIGURE 2 TYPICAL THERMAL RESISTANCE 1000 500 400 300 200 100 50 40 30 20 10 5 4 3 2 1 .1 .2 .5 1 2 5 10 20 50 100 OPERATING CURRENT IZT (mA) FIGURE 3 ZENER IMPEDANCE VS.
