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 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: mail@cdi-diodes.com 1N4916 1000 ZENER IMPEDANCE ZZT (OHMS) 500 thru 1N4932A 200 100 50 20 10 2 4 6 8 10 12 OPERATING CURRENT lZT (mA) FIGURE 2 ZENER IMPEDANCE VS.
