c. t = 5 s.
d. See Solder Profile (http://www.vishay.com/ppg?73257). The 1206-8 ChipFET is a leadless package. The end of the lead terminal is exposed
copper (not plated) as a result of the singulation process in manufacturing. A solder fillet at the exposed copper tip cannot be guaranteed and
is not required to ensure adequate bottom side solder interconnection.
e. Rework Conditions: manual soldering with a soldering iron is not recommended for leadless components.
f. Maximum under Steady State conditions is 95 °C/W.

* The power dissipation PD is based on TJ(max) = 150 °C, using junction-to-case thermal resistance, and is more useful in settling the upper
dissipation limit for cases where additional heatsinking is used. It is used to determine the current rating, when this rating falls below the package
limit.

Single-Channel 1206-8 ChipFETr Power MOSFET Recommended
Pad Pattern and Thermal Performance
INTRODUCTION
New Vishay Siliconix ChipFETs in the leadless 1206-8
package feature the same outline as popular 1206-8 resistors
and capacitors but provide all the performance of true power
semiconductor devices. The 1206-8 ChipFET has the same
footprint as the body of the LITTLE FOOTR TSOP-6, and can
be thought of as a leadless TSOP-6 for purposes of visualizing
board area, but its thermal performance bears comparison
with the much larger SO-8.

This technical note discusses the single-channel ChipFET
1206-8 pin-out, package outline, pad patterns, evaluation
board layout, and thermal performance.

PIN-OUT
Figure 1 shows the pin-out description and Pin 1 identification
for the single-channel 1206-8 ChipFET device. The pin-out is
similar to the TSOP-6 configuration, with two additional drain
pins to enhance power dissipation and thermal performance.
The legs of the device are very short, again helping to reduce
the thermal path to the external heatsink/pcb and allowing a
larger die to be fitted in the device if necessary.

The pad pattern with copper spreading shown in Figure 2
improves the thermal area of the drain connections (pins
1,2,3,6.7,8) while remaining within the confines of the basic
footprint. The drain copper area is 0.0054 sq. in. or
3.51 sq. mm). This will assist the power dissipation path away
from the device (through the copper leadframe) and into the
board and exterior chassis (if applicable) for the single device.
The addition of a further copper area and/or the addition of vias
to other board layers will enhance the performance still further.
An example of this method is implemented on the
Vishay Siliconix Evaluation Board described in the next
section (Figure 3).

MOSFETs,

power dissipation MOSFET applications, but power
semiconductor performance requires a greater copper pad
area, particularly for the drain leads.

FIGURE 2. Footprint With Copper Spreading
THE VISHAY SILICONIX EVALUATION
BOARD FOR THE SINGLE 1206-8
The ChipFET 1206-08 evaluation board measures 0.6 in by
0.5 in. Its copper pad pattern consists of an increased pad area
around the six drain leads on the top-side—approximately
0.0482 sq. in. 31.1 sq. mm—and vias added through to the
underside of the board, again with a maximized copper pad
area of approximately the board-size dimensions. The outer
package outline is for the 8-pin DIP, which will allow test
sockets to be used to assist in testing.
The thermal performance of the 1206-8 on this board has been
measured with the results following on the next page. The
testing included comparison with the minimum recommended
footprint on the evaluation board-size pcb and the industry
standard one-inch square FR4 pcb with copper on both sides
of the board.

FIGURE 3.
Junction-to-Foot Thermal Resistance
(the Package Performance)
Thermal performance for the 1206-8 ChipFET measured as
junction-to-foot thermal resistance is 15_C/W typical, 20_C/W
maximum for the single device. The “foot” is the drain lead of
the device as it connects with the body. This is identical to the
SO-8 package RQjf performance, a feat made possible by
shortening the leads to the point where they become only a
small part of the total footprint area.
Junction-to-Ambient Thermal Resistance
(dependent on pcb size)
The typical RQja for the single-channel 1206-8 ChipFET is
80_C/W steady state, compared with 68_C/W for the SO-8.
Maximum ratings are 95_C/W for the 1206-8 versus 80_C/W
for the SO-8.
The results show that a major reduction can be made in the
thermal resistance by increasing the copper drain area. In this
example, a 45_C/W reduction was achieved without having to
increase the size of the board. If increasing board size is an
option, a further 33_C/W reduction was obtained by
maximizing the copper from the drain on the larger 1” square
pcb.

To aid comparison further, Figure 4 illustrates ChipFET 1206-8
thermal performance on two different board sizes and three
different pad patterns. The results display the thermal
performance out to steady state and produce a graphic
account of how an increased copper pad area for the drain
connections can enhance thermal performance. The
measured steady state values of RQja for the single 1206-8
ChipFET are :

SUMMARY
The thermal results for the single-channel 1206-8 ChipFET
package display similar power dissipation performance to the
SO-8 with a footprint reduction of 80%. Careful design of the
package has allowed for this performance to be achieved. The
short leads allow the die size to be maximized and thermal
resistance to be reduced within the confines of the TSOP-6
body size.
