DO - 35 outline. LEAD MATERIAL: Copper clad steel. LEAD FINISH: Tin / Lead THERMAL RESISTANCE: (ROJEC): 250 C/W maximum at L = .375 inch THERMAL IMPEDANCE: (ZOJX): 35 C/W maximum POLARITY: Diode to be operated with the banded (cathode) end positive. MOUNTING POSITION: Any. NOTE 1 NOTE 2 NOTE 3 Zener voltage tolerance on "B"suffix is + 5%. Suffix letter A denotes +10%. No Suffix denotes + 20% tolerance, "C" suffix denotes + 2% and "D" suffix denotes + 1%. Zener voltage is measured with the device junction in thermal equilibrium at an ambient temperature of 25C + 3C. Zener impedance is derived by superimposing on 1 A 60Hz rms a.c. current ZT equal to 10% of 1 ZT 6 LAKE STREET, LAWRENCE, MASSACHUSETTS 01841 PHONE (978) 620-2600 FAX (978) 689-0803 WEBSITE: http://www.microsemi.com 23 1N957 thru 1N986B INCLUDING -1 VERSIONS FIGURE 2 Pd, Rated Power Dissipation (mW) 500 400 300 200 100 0 0 25 50 75 100 125 150 175 TA, Ambient temperature (C) POWER DERATING CURVE 1000 500 400 300 200 ZENER IMPEDANCE ZZT (OHMS) 3. 3 VO LT 27 100 VO LT 5. 1 VO LT 50 40 30 20 11 VO LT 10 6.2 5 4 3 2 VO LT 1 .1 .2 .3 .4 .5 1 25 10 20 OPERATING CURRENT lZT (mA) 30 40 50 100 FIGURE 3 ZENER IMPEDANCE VS.
