The RΘJA of the CS3717A can be reduced by soldering the
Gnd pins to a suitable copper area of the printed circuit
board or to an external heatsink.
The diagram of fig. 2 shows the maximum dissipated
power Ptot and the RΘJA as a function of the side “l ” of
two equal square copper areas having a thickness of 35
(see fig. 1). In addition, it is possible to use an external
heatsink (see fig. 3). During soldering the pins tempera-
ture must not exceed 260°C and the soldering time must
not be longer than 12 seconds.
The external heatsink or printed circuit copper area must
be connected to electrical ground.
