No Suffix denotes + 10% tolerance. "C" suffix denotes + 2% tolerance and "D" suffix denotes + 1% tolerance. 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.
