No Suffix denotes + 10% tolerance, "C" suffix denotes + 2% tollerance 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 1 ZT A 60Hz rms a.c. current equal to 10% of 1ZT
