MAXIMUM RATINGS

Operating Temperature: -65°C to +175°C Storage Temperature: -65°C to +175°C Forward Voltage @ 200 mA: 1.5 Volts maximum

NOTE 1

Zener voltage range equals “nominal Zener voltage” (see table) +

5%, for “B” Suffix types. “A” Suffix denotes + 10%. No Suffix denotes + 20%. "C" suffix = +

2% tolerance and

"D" suffix = +

1% tolerance.

NOTE 2

Zener impedance is derived by superimposing on lZTA 60 Hz rms a.c. current equal to 10% of l

NOTE 3

Zener voltage is read using a pulse measment, 10 miliseconds maximum.
