Note 1: Stresses beyond those listed under Absolute Maximum Ratings 
may cause permanent damage to the device. Exposure to any Absolute 
Maximum Rating condition for extended periods may affect device 
reliability and lifetime.
Note 2: All currents into pins are positive.
Note 3: Limits on the maximum rating is defined as whichever limit occurs 
first. An internal clamp limits the GATE pin to a maximum of 12V above 
source. Driving this pin to voltages beyond the clamp may damage the 
device.
Note 4: T
J
 is calculated from the ambient temperature, T
A
, and power 
dissipation, P
D
, according to the formula:
 T

 = T
