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 specified mV at any discrete temperature between the established limits, per JEDEC standard No.5. NOTE 3 Zener voltage range equals 19.2 volts + 5%. 22 COREY STREET, MELROSE, MASSACHUSETTS 02176 PHONE (781) 665-1071 FAX (781) 665-7379 WEBSITE: http://www.cdi-diodes.com E-mail: [email protected] 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.
