Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits.
Note 2: Thermal resistance of Z package is 60˚C/W θ
JC
, 232˚C/W θ
JA
at still air, and 88˚C/W at 400 ft/min of air. The M package θ
JA
is 180˚C/W in still air. The
maximum junction temperature shall not exceed 125˚C on electrical parameters.
Note 3: To ensure constant junction temperature, low duty cycle pulse testing is used.
