NOTE 1
The JEDEC type numbers shown above have a standard tolerance of
+ 5% oF the nominal Zener voltage. Vz is measured with the diode in
thermal equilibrium at 25°C + 3°C.
NOTE 2
VZ@ 100
μ
A minus VZ@ 10
μ
A.
NOTE 3
Zener voltage is read using a pulse measurement, 10 milliseconds maximum.
MAXIMUM RATINGS
Operating Temperatures: -65°C to +175°C
Storage Temperatures: -65°C to +175°C
Forward Voltage @ 200 mA: 1.5 Volts maximum
ELECTRICAL CHARACTERISTICS
@ 25°C, unless otherwise specified.
