NOTE 1
Zener voltage tolerance on "A" suffix is +5%. 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 25C, +3C.
NOTE 3
Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal
to 10% of 1ZT.
