Zener voltage tolerance on "A" suffix is +5%. No Suffix denotes + 10% tolerance,
"C" suffix denotes + 2% tollerance and "D" suffix denotes + 1% tolerance.
Zener voltage is measured with the device junction in thermal equilibrium at an ambient
temperature of 25°C + 3°C.
Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal
to 10% of 1ZT
POLARITY:
Diode to be operated with
the banded (cathode) end positive.
MOUNTING POSITION:
Any.
