THERMAL DATA

DM PACKAGE:

THERMAL RESISTANCE-JUNCTION TO AMBIENT, θJA

LP PACKAGE:

165°C/W

THERMAL RESISTANCE-JUNCTION TO AMBIENT, θJA

156°C/W

Junction Temperature Calculation: TJ = TA + (PD x θJA).

The

θ

JA

numbers

are

guidelines

for

the

thermal

performance

of

the

device/pc-board

system.

All of the above assume no ambient airflow
