Applications Information
Thermal Model
The steady state thermal model for the HSSR-7110 is
shown in Figure 21. The thermal resistance values given
in this model can be used to calculate the temperatures
at each node for a given operating condition. The thermal
resistances between the LED and other internal nodes
are very large in comparison with the other terms and
are omitted for simplicity. The components do, however,
interact indirectly through θ
thermal resistance. �ll heat generated flows through
θ
The value of θ
design and is, therefore, determined by the designer.
The maximum value for each output MOSFET junction-
to-case thermal resistance is specified as 15�C��. The
thermal resistance from FET driver junction-to-case is also
15�C��. The power dissipation in the FET driver, however,
is negligible in comparison to the MOSFETs.

On-Resistance and Rating Curves
The output on-resistance, R
sheet, is the resistance measured across the output
contact when a pulsed current signal (I
applied to the output pins. The use of a pulsed signal (≤
30 ms) implies that each junction temperature is equal
to the ambient and case temperatures. The steadystate
resistance, R
sistance measured across the output contact when a DC
current signal is applied to the output pins for a duration
sufficient to reach thermal equilibrium. R
effects of the temperature rise of each element in the
thermal model. Rating curves are shown in Figures 2 and
4. Figure 2 specifies the maximum average output current
allowable for a given ambient temperature. Figure 4
specifies the output power dissipation allowable for a
given ambient temperature. �bove 55�C (for θ
