Lead Temperature (Soldering, 60 sec) 300°C

ESD Susceptibility 4 kV

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

Junction-to-air thermal resistance (θ

JA

) is specified for the worst-

case conditions, that is, a device soldered in a printed circuit

board (PCB) for surface-mount packages. θ

JA

is determined

according to JEDEC JESD51-9 on a 4-layer PCB with natural

convection cooling.
