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 θJC, 232˚C/W θJA at still air, and 88˚C/W at 400 ft/min of air. The M package θJA 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.
