NOTE 3

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.
