2 Junction-to-case resistance is applicable to components featuring a

preferential flow direction, for example, components mounted on a heat

sink. Junction-to-ambient resistance is more useful for air-cooled PCB-

mounted components.

Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress

rating only; functional operation of the device at these or any

other conditions above those indicated in the operational

section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability.
