No suffix = + 10% tolerance on nominal Zener voltage, suffix “A” signifies +5%, suffix “C”
signifies + 2%, suffix “D” signifies + 1%.
Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal to
10% of 1ZT.
Zener voltage is measured with the device junction in thermal equilibrium at an ambient
temperature of 25°C + 3°C.
