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° + 3°C.
