Note 1:
Absolute Maximum Ratings are limits beyond which damage to the device may occur. For guaranteed performance limits and associated test conditions, see
the Electrical Characteristics tables.
Note 2:
To ensure constant junction temperature, low duty cycle pulse testing is used.
Note 3:
Limits appearing in

Note 4:
The maximum allowable power dissipation is a function of the maximum junction temperature T
J
(MAX), the junction-to ambient thermal resistance
θ

and the
ambient temperature TA. The maximum allowable power dissipation at any ambient temperature is calculated using:
