FIGURE 1 DESIGN DATA CASE: Hermetically sealed glass case. DO – 35 outline. LEAD MATERIAL: Copper clad steel. LEAD FINISH: Tin / Lead POLARITY: Diode to be operated with the banded (cathode) end positive. MOUNTING POSITION: ANY. NOTE 2 The maximum allowable change observed over the entire temperature range i.e., the diode voltage will not exceed the speci½ed mV at any discrete temperature between the established limits, per JEDEC standard No.5. NOTE 3 Zener voltage range equals 9.1 volts + 5%. 6 LAKE STREET, LAWRENCE, MASSACHUSETTS 01841 PHONE (978) 620-2600 FAX (978) 689-0803 WEBSITE: http://www.microsemi.com 49 thru 1N4774A Pd, Rated Power Dissipation (mW) 1N4765 600 500 400 300 200 100 0 0 25 50 75 100 125 150 TL, Lead temperature (C°) 3/8” from body FIGURE 2 CHANGE IN TEMPERATURE COEFFICIENT (%/°C) POWER DERATING CURVE 1000 500 100 50 10 1 2 OPERATING CURRENT lZT (mA) 3 FIGURE 3 ZENER IMPEDANCE VS.
