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 1 NOTE 2 The maximum allowable change observed over the entire temperature range i.e., the diode voltage will not exceed the specified mV at any discrete temperature between the established limits, per JEDEC standard No.5. Zener impedance is derived by superimposing on lZT A 60Hz rms a.c. current equal to 10% of lZT. 2 2 COREY STREET, MELROSE, MASSACHUSETTS 02176 PHONE (781) 665-1071 FAX (781) 665-7379 WEBSITE: http://www.cdi-diodes.com E-mail: mail@cdi-diodes.com 1N4565 +.0015 +.0010 +.0005 0 CHANGE IN TEMPERATURE COEFFICIENT ( %/°C) -.0005 -.0010 -.0015 thru 1N4584A INCLUDING -1 VERSIONS 1N4570-1N4574 1N4565-1N4569 .1 .2 .3 .4 .5 .6 .7 .8 OPERATING CURRENT lZT (mA) .9 .25 .5 1.0 1.5 2.0 OPERATING CURRENT lZT (mA) +.0010 +.0005 0 -.0005 -.0010 -.0015 1N4575-1N4579 1N4580-1N4584 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 OPERATING CURRENT lZT (mA) 4.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 5.5 OPERATING CURRENT lZT (mA) 6.0 TYPICAL CHANGE OF TEMPERATURE COEFFICIENT WITH CHANGE IN OPERATING CURRENT 10000 5000 ZENER IMPEDANCE ZZT (OHMS) 10000 1N4565-1N4574 ZENER IMPEDANCE ZZT (OHMS) 5000 1N4575-1N4584 1000 500 1000 500 100 50 100 50 10 .25 .5 1.0 1.5 2.0 2.5 3.0 3.5 OPERATING CURRENT IZT (mA) 10 1.0 2.0 3.0 4.0 5.0 6.0 OPERATING CURRENT IZT (mA) ZENER IMPEDANCE VS.
