THERMAL PERFORMANCE
Junction-to-Foot Thermal Resistance
(Package Performance)
The junction to foot thermal resistance is a useful method of
comparing different packages thermal performance.
A helpful way of presenting the thermal performance of the
6-Pin SC-70 copper leadframe device is to compare it to the
traditional Alloy 42 version.
Thermal performance for the 6-pin SC-70 measured as
junction-to-foot thermal resistance, where the “foot” is the
drain lead of the device at the bottom where it meets the PCB.
The junction-to-foot thermal resistance is typically 40_C/W in
the copper leadframe and 163_C/W in the Alloy 42 leadframe
— a four-fold improvement. This improved performance is
obtained by the enhanced thermal conductivity of copper over
Alloy 42.
Power Dissipation
The typical RqJA for the single 6-pin SC-70 with copper
leadframe is 103_C/W steady-state, compared with 212_C/W
for the Alloy 42 version. The figures are based on the 1-inch2
FR4 test board. The following example shows how the thermal
resistance impacts power dissipation for the two different
leadframes at varying ambient temperatures.

As can be seen from the calculations above, the compact 6-pin
SC-70 copper leadframe LITTLE FOOT power MOSFET can
handle up to 1 W under the stated conditions.
Testing
To further aid comparison of copper and Alloy 42 leadframes,
Figure 5 illustrates single-channel 6-pin SC-70 thermal
performance on two different board sizes and two different pad
patterns. The measured steady-state values of RqJA for the
two leadframes are as follows:
LITTLE FOOT 6-PIN SC-70
Alloy 42
Copper
1) Minimum recommended pad pattern on
the EVB board V (see Figure 3.
329.7_C/W
208.5_C/W
2) Industry standard 1-inch2 PCB with
maximum copper both sides.
211.8_C/W
103.5_C/W
The results indicate that designers can reduce thermal
resistance (RqJA) by 36% simply by using the copper
leadframe device rather than the Alloy 42 version. In this
example, a 121_C/W reduction was achieved without an
increase in board area. If increasing in board size is feasible,
a further 105_C/W reduction could be obtained by utilizing a
1-inch2 square PCB area.
The copper leadframe versions have the following suffix:
Single:
Si14xxEDH
Dual:
Si19xxEDH
Complementary: Si15xxEDH
