No Suffix denotes + 10% tolerance, suffix denotes + 2% tollerance and suffix denotes + 1% tolerance. 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 ZT to 10% of 1 ZT 6 LAKE STREET, LAWRENCE, MASSACHUSETTS 01841 PHONE (978) 620-2600 FAX (978) 689-0803 WEBSITE: 1N746 thru 1N759A and 1N4370 thru1N4372A INCLUDING -1 VERSIONS 500 400 300 200 100 0 0 25 50 75 100 125 150 175 T , Lead temperature (C) 3/8 from body L POWER DERATING CURVE 100 50 20 10 5 2 1 4 6 10 20 40 60 100 FIGURE 3 operating current (mA) ZENER IMPEDANCE VS.
