NOTE 1 Suffix "B" voltage range equals nominal Zener voltage + 5%. Suffix "A" equals
+ 10%. No Suffix equals + 20%. Zener voltage is read using a pulse
measurement, 10 milliseconds maximum. "C" suffix = + 2% and "D" suffix = +1%.
NOTE 2 Zener impedance is derived by superimposing on lZT A 60Hz rms a.c.
current equal to 10% of lZT.
NOTE 3
VZ is the maximum difference between VZ @ 1ZT and VZ at 1ZL measured
with the device junction in thermal equilibrium at an ambient temperature of
+25 + 3C.
