LEAD FINISH: Tin / Lead POLARITY: Diode to be operated with the banded (cathode) end positive. MOUNTING POSITION: Any. NOTE 1 Zener impedance is derived by superimposing on lZT A 60Hz rms a.c. current equal to 10% of lZT. 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 19.2 volts + 5%. 6 LAKE STREET, LAWRENCE, MASSACHUSETTS 01841 PHONE (978) 620-2600 FAX (978) 689-0803 WEBSITE: http://www.microsemi.com 55 1N4916 thru 1N4932A ZENER IMPEDANCE ZZT (OHMS) 1000 500 200 100 50 20 10 2 4 6 8 10 12 OPERATING CURRENT lZT (mA) FIGURE 2 1N4916—1N4918 1N4919—1N4921 .2 .4 .6 .8 OPERATING CURRENT lZT (mA) 0.5 1.0 1.5 2.0 OPERATING CURRENT lZT (mA) 1N4922—1N4924 +.0015 +.0010 +.0005 0 -.0005 -.0010 -.0015 CHANGE IN TEMPERATURE COEFFICIENT ( %/°C) CHANGE IN TEMPERATURE COEFFICIENT ( %/°C) ZENER IMPEDANCE VS.
