Notes
-
Use
appropriate power supply. Transient reverse current greater than 25μA and
/or reverse voltage >2V will destroy the unit.
-
A
dry environment should be provided when storing or operating a device at
temperatures below the ambient dew point. Failure to do so will cause
condensation on the unit and will destroy it.
-
Output
powers in excess of specification data will accelerate device aging.
-
Operating
units require adequate heat dissipating or refrigeration.
-
Operation
at higher temperatures will accelerate device aging, increase threshold
current and lower slope efficiency.
-
To
C-block unit, be
sure to keep the diode clean.
Note: The above specifications are
subject to change
without notice.
