Suffix "B" = 5% tolerance on nominal Zener voltage, suffix "C" signifies 2%.
Zener voltage is measured with the device junction in thermal equilibrium at an ambient temperature of 25°C + 3°C
temperature of 25°C +
Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal to
10% of1ZT.
Reverse leakage currents are measured at VR as shown on the table.
VZ is the maximum difference between VZ at lZT and VZ at lZL measured
with the device junction in thermal equilibrium.
