NOTE 1

Zener voltage tolerance on "A" suffix is +5%. No Suffix denotes + 10% tolerance,

"C" suffix denotes + 2% tollerance and "D" suffix denotes + 1% tolerance.

POLARITY: Diode to be operated with

the banded (cathode) end positive.

NOTE 2

NOTE 3

Zener voltage is measured with the device junction in thermal equilibrium at an ambient

temperature of 25°C + 3°C.

MOUNTING POSITION: Any.

Zener impedance is derived by superimposing on 1 A 60Hz rms a.c. current equal

to 10% of 1
