Thermal resistances corresponding to other copper areas
can be obtained from Figure 23 or by calculation using
Equation 2. R
θ
JA
is defined as the natural log of the area
times a coefficient added to a constant. The area, in square
inches is the top copper area including the gate and source
pads.

While Equation 2 describes the thermal resistance of a
single die, several of the new UltraFETs are offered with two
die in the SOP-8 package. The dual die SOP-8 package
introduces an additional thermal component, thermal
coupling resistance,
R
θβ
. Equation 3 describes
R
θβ
as a
function of the top copper mounting pad area.

The thermal coupling resistance vs. copper area is also
graphically depicted in Figure 23. It is important to note the
thermal resistance (R
θ
JA
) and thermal coupling resistance
(

define the junction temperature of the respective

die. The steady state junction temperature can be calculated
using Equation 4 for die 1and Equation 5 for die 2.
Example: Use Equation 4 to calculate T

calculate T

dissipating 0.5 Watts; die 1 is dissipating 0 Watts; the

The transient thermal impedance (Z
θ
JA
) is also effected by
varied top copper board area. Figure 24 shows the effect of
copper pad area on single pulse transient thermal
impedance. Each trace represents a copper pad area in
square inches corresponding to the descending list in the
graph. SPICE and SABER thermal models are provided for
each of the listed pad areas.
Copper pad area has no perceivable effect on transient
thermal impedance for pulse widths less than 100ms. For
pulse widths less than 100ms the transient thermal
impedance is determined by the die and package. Therefore,
CTHERM1 through CTHERM5 and RTHERM1 through
RTHERM5 remain constant for each of the thermal models. A
listing of the model component values is available in Table 1.
