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. 22 COREY STREET, MELROSE, MASSACHUSETTS 02176 PHONE (781) 665-1071 FAX (781) 665-7379 WEBSITE: http://www.cdi-diodes.com E-mail: [email protected] 1N4565 thru 1N4584A INCLUDING -1 VERSIONS +.0015 1N4565-1N4569 +.0010 1N4570-1N4574 +.0005 -.0005 -.0010 -.0015 .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) 1N4580-1N4584 1N4575-1N4579 +.0010 +.0005 0 -.0005 -.0010 -.0015 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 10000 5000 5000 1N4565-1N4574 ZENER IMPEDANCE ZZT (OHMS) ZENER IMPEDANCE ZZT (OHMS) CHANGE IN TEMPERATURE COEFFICIENT ( %/°C) 0 1000 500 100 50 10 1N4575-1N4584 1000 500 100 50 10 .25 .5 1.0 1.5 2.0 2.5 3.0 3.5 OPERATING CURRENT IZT (mA) 1.0 2.0 3.0 4.0 5.0 6.0 OPERATING CURRENT IZT (mA) ZENER IMPEDANCE VS.
