FSCTxxA-UH5
8/11
Two components should be used to improve the heat exchange between the FSCT die and the heat sink,
that the temperature has to be monitored. These components are:
I
A thermal interface pad, in order to reduce the impact of air voids on the thermal impedance and to en-
sure an electrical insulation (if needed)
I
A clip to push the IPPAK against the heat sink and then to reduce also the interface thermal imped-
ance.
Several clips can be used depending on the heat sink type:
I
Saddle clips (cf. figure 9) for slim heat sink;
I
U-clips (cf. figure 10) for thick heat sink
I
Dedicated clips for special shape heat sink.

ItcanbenoticedthatthethicknessoftheIPPAKpackage(2.3+/-0.1mm)issimilartothoseofSOT-32and
SOT-82 (2.55 +/- 0.15 mm). The same clips can so be used for all these packages.
3.3 Temperature measurement error
Firstly, the time constant between a temperature variation on the external side on the IPPAK copper tab,
and the silicon die is in the range of a few hundred of milliseconds. As temperature phenomena are ex-
tremelyslowforthetargetedapplications(thetemperatureofaMOSFETheatsink,increasestypicallywith
an1°Cpersecondrate,inapowersupply),theFSCTisabletoreactimmediatelytoover-heatingevents.
Moreover, the very low junction to case thermal resistance (3 °C/W) reduces as much as possible the tem-
perature measurement error.
We calculate, in the following, this error considering both the package and the heatsink-Tab interface ther-
mal resistances (figure 11).

IPPAK Heatsink Interface.
Several companies offer adhesive and isolating
materials to be used as interface between elec-
tronic devices and a heat sink. These interfaces
can be provided with a shape dedicated for the
Tab foot print. For the IPPAK package, users could
choose a shape dedicated for SOT-32, SOT-82 or
even TO-126 or TO-220 packages (the more can
do the less).
