Suffix letter “A” denotes + 10%. No Suffix denotes + 20%. "C" suffix denotes + 2%, and "D" suffix denotes + 1%. NOTE 2 Zener voltage is measured with the device junction in thermal equilibrium at an ambient temperature of 25°C + 3°C. NOTE 3 Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal to 10% of 1ZT.
