NOTE 1
Zener voltage range equals nominal voltage +5% for "A" Suffix types. No Suffix denotes + 10%.
"C" suffix = + 2% and "D" suffix = + 1%.
NOTE 2
Zener voltage is read using a pulse measurement, 10 milliseconds maximum.
NOTE 3
Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal
to 10% of 1ZT.
MAXIMUM RATINGS
Operating Temperature: -65C to +175C
Storage Temperature: -65C to +175C
Forward Voltage @ 200mA: 1.5 volts maximum
