NOTE 1 Zener voltage tolerance on "A" suffix is +5%. 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
