PowerPAK® 1212 Mounting and Thermal Considerations
Johnson Zhao
AN822
Vishay Siliconix
MOSFETs for switching applications are now available
with die on resistances around 1 mΩ and with the
capability to handle 85 A. While these die capabilities
represent a major advance over what was available
just a few years ago, it is important for power MOSFET
packaging technology to keep pace. It should be obvious that degradation of a high performance die by the
package is undesirable.
technology that addresses these issues. The PowerPAK
1212-8 provides ultra-low thermal impedance in a
small package that is ideal for space-constrained
applications. In this application note, the PowerPAK
1212-8’s construction is described. Following this,
mounting information is presented. Finally, thermal
and electrical performance is discussed.
THE PowerPAK PACKAGE
The PowerPAK 1212-8 package (Figure 1) is a derivative of PowerPAK SO-8. It utilizes the same packaging
technology, maximizing the die area. The bottom of the
die attach pad is exposed to provide a direct, low resistance thermal path to the substrate the device is
mounted on. The PowerPAK 1212-8 thus translates
the benefits of the PowerPAK SO-8 into a smaller
package, with the same level of thermal performance.
(Please refer to application note “PowerPAK SO-8
Mounting and Thermal Considerations.”)
PowerPAK is a new package
The PowerPAK 1212-8 has a footprint area comparable to TSOP-6. It is over 40 % smaller than standard
TSSOP-8. Its die capacity is more than twice the size
of the standard TSOP-6’s. It has thermal performance
an order of magnitude better than the SO-8, and 20
times better than TSSOP-8. Its thermal performance is
better than all current SMT packages in the market. It
will take the advantage of any PC board heat sink
capability. Bringing the junction temperature down also
increases the die efficiency by around 20 % compared
with TSSOP-8. For applications where bigger packages are typically required solely for thermal consideration, the PowerPAK 1212-8 is a good option.
Both the single and dual PowerPAK 1212-8 utilize the
same pin-outs as the single and dual PowerPAK SO-8.
The low 1.05 mm PowerPAK height profile makes both
versions an excellent choice for applications with
space constraints.
PowerPAK 1212 SINGLE MOUNTING

thermal performance see Application Note 826,

This land pattern can be extended to the left, right, and
top of the drawn pattern. This extension will serve to
increase the heat dissipation by decreasing the thermal resistance from the foot of the PowerPAK to the
PC board and therefore to the ambient. Note that
increasing the drain land area beyond a certain point
will yield little decrease in foot-to-board and foot-toambient thermal resistance. Under specific conditions

experiments have found that adding copper beyond an

The gap between the two drain pads is 10 mils. This

This land pattern can be extended to the left, right, and

increase the heat dissipation by decreasing the thermal resistance from the foot of the PowerPAK to the

Figure 3. Solder Reflow Temperatures and Time Durations
A basic measure of a device’s thermal performance is
the junction-to-case thermal resistance, Rθjc, or the
junction to- foot thermal resistance, Rθjf. 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 a
comparison of the PowerPAK 1212-8, PowerPAK SO-8,
standard TSSOP-8 and SO-8 equivalent steady state
performance.
By minimizing the junction-to-foot thermal resistance, the
MOSFET die temperature is very close to the temperature of the PC board. Consider four devices mounted on
a PC board with a board temperature of 45 °C (Figure 4)
Suppose each device is dissipating 2 W. Using the junction-to-foot thermal resistance characteristics of the
PowerPAK 1212-8 and the other SMT packages, die
temperatures are determined to be 49.8 °C for the PowerPAK 1212-8, 85 °C for the standard SO-8, 149 °C for
standard TSSOP-8, and 125 °C for TSOP-6. This is a
4.8 °C rise above the board temperature for the PowerPAK 1212-8, and over 40 °C for other SMT packages. A
4.8 °C rise has minimal effect on r

Spreading Copper
Designers add additional copper, spreading copper, to
the drain pad to aid in conducting heat from a device. It
is helpful to have some information about the thermal
performance for a given area of spreading copper.
Figure 5 and Figure 6 show the thermal resistance of a
PowerPAK 1212-8 single and dual devices mounted on
a 2-in. x 2-in., four-layer FR-4 PC boards. The two internal layers and the backside layer are solid copper. The
internal layers were chosen as solid copper to model the
large power and ground planes common in many applications. The top layer was cut back to a smaller area and
at each step junction-to-ambient thermal resistance
measurements were taken. The results indicate that an
area above 0.2 to 0.3 square inches of spreading copper
.
gives no additional thermal performance improvement.
A subsequent experiment was run where the copper on
the back-side was reduced, first to 50 % in stripes to
mimic circuit traces, and then totally removed. No significant effect was observed.

CONCLUSIONS
As a derivative of the PowerPAK SO-8, the PowerPAK
1212-8 uses the same packaging technology and has
been shown to have the same level of thermal performance while having a footprint that is more than 40 %
smaller than the standard TSSOP-8.
Recommended PowerPAK 1212-8 land patterns are
provided to aid in PC board layout for designs using this
new package.
The PowerPAK 1212-8 combines small size with attractive thermal characteristics. By minimizing the thermal
rise above the board temperature, PowerPAK simplifies
thermal design considerations, allows the device to run
cooler, keeps r
low, and permits the device to
