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