POLARITY: Diode to be operated with
the banded (cathode) end positive.

NOTE 3
Zener voltage tolerance on "B"suffix is + 5%. Suffix letter A denotes +10%. No Suffix
denotes + 20% tolerance, "C" suffix denotes + 2% and "D" suffix denotes + 1%.
MOUNTING POSITION: Any.
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 1 A 60Hz rms a.c. current
ZT
equal to 10% of 1
