† Mounted on FR4 board, 25mm x 25mm x 1.57mm. Stresses beyond those listed under
“Absolute Maximum Ratings” may cause permanent damage to the device. These are
stress ratings only, and functional operation of the device at these or any other conditions
beyond those indicated in the operational sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended periods may affect device
reliability.
Electrical Characteristics (The * denotes the specifications which apply over the full operating junction temperature range of
-40°C < TA < +85°C, otherwise the specifications are at TA=25°C, VDRAIN=50V, unless otherwise noted)
