Design-In Principles
> The RTS should be placed as close as possible to the heat
source (power semiconductor).
> Max. nominal current depends on ambient temperature and on
the PCB track implementation (see Derating Curves).
> The derating curves were generated using a PCB acc. to
IEC 60127-4 with a layer width of 20 mm.
> If operating current is higher than allowed, consider using two
RTS in parallel. This doubles the max. current value in the
derating curve.
