FIGURE 1
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,
per JEDEC standard No.5.
NOTE 3 Zener voltage range equals 12.8 volts + 5%.
