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