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 25C + 3C.
NOTE 2
VZ @ 100
A minus VZ @ 10
A.
NOTE 3
Zener voltage is read using a pulse measurement, 10 milliseconds maximum.
MAXIMUM RATINGS
Operating Temperatures: -65C to +175C
Storage Temperatures: -65C to +175C
Forward Voltage @ 200 mA: 1.5 Volts maximum
