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.

THERMAL RESISTANCE

θJA is specified for the worst-case conditions, that is, a device

soldered in a circuit board for surface-mount packages.

°C/W

1 Based on JEDEC 2S2P PCB.

THERMAL CONDITIONS

To ensure correct operation of the device, the case temperature

(TCASE) must be kept below 121°C to keep the junction tempera-

ture (TJ) below the maximum allowed, 125°C.
