Equation 1 mathematically represents the relationship and
serves as the basis for establishing the rating of the part.
The transient thermal impedance (Z ) is also effected
qJA
by varied top copper board area. Figure 21 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 100 ms. For
pulse widths less than 100 ms 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.

In using surface mount devices such as the SO8 package,
the environment in which it is applied will have a significant
influence on the part’s current and maximum power
dissipation ratings. Precise determination of PDM is complex
and influenced by many factors:
1. Mounting pad area onto which the device is
attached and whether there is copper on one side
or both sides of the board.
2. The number of copper layers and the thickness of
the board.
3. The use of external heat sinks.
4. The use of thermal vias.
5. Air flow and board orientation.

defines the R for the device as a function of the top copper

(component side) area. This is for a horizontally positioned
FR−4 board with 1 oz copper after 1000 seconds of steady
state power with no air flow. This graph provides the
necessary information for calculation of the steady state
junction temperature or power dissipation. Pulse
applications can be evaluated using the onsemi device Spice
thermal model or manually utilizing the normalized
maximum transient thermal impedance curve.
