THERMAL PERFORMANCE
A basic measure of a device’s thermal performance is the
junction-to-case
thermal
resistance,
Rqjc,
or
the
junction-to-foot thermal resistance, Rqjf. This parameter is
measured for the device mounted to an infinite heat sink and
is therefore a characterization of the device only, in other
words, independent of the properties of the object to which the
device is mounted. Table 1 shows the thermal performance
of the TSOP-6.

SYSTEM AND ELECTRICAL IMPACT OF
TSOP-6
In any design, one must take into account the change in
MOSFET rDS(on) with temperature (Figure 4).
