VISHAY DG468

DG467, DG468
Vishay Siliconix
Low Power, High Voltage SPST Analog Switches
DESCRIPTION
FEATURES
The DG467 and DG468 are dual supply single-pole/singlethrow (SPST) switches. On resistance is 10  maximum and
flatness is 2  max over the specified analog signal range.
These analog switches were designed to provide high
speed, low error switching of precision analog signals. The
primary application areas are in the routing and switching in
telecommunications and test equipment. Combining low
power, low leakages, low on-resistance and small physical
size, the DG467/468 are also ideally suited for portable and
battery powered industrial and military equipment.
• Halogen-free according to IEC 61249-2-21
Definition
• ± 15 V Analog Signal Range
• On-Resistance - RDS(on): 10  max
• Fast Switching Action - TON: 100 ns
• VL Logic Supply Not Required
• TTL CMOS Input Compatible
• Rail To Rail Signal Handling
• Dual Or Single Supply Operation
• Compliant to RoHS Directive 2002/95/EC
BENEFITS
The DG467 has one normally closed switch, while the
DG468 switch is normally open. They operate either from a
single + 7 V to 36 V supply or from dual ± 4.5 V to ± 20 V
supplies. They are offered in the very popular, small TSOP6
package.

Mounting LITTLE FOOTR TSOP-6 Power MOSFETs
Surface mounted power MOSFET packaging has been based on
integrated circuit and small signal packages. Those packages
have been modified to provide the improvements in heat transfer
required by power MOSFETs. Leadframe materials and design,
molding compounds, and die attach materials have been
changed. What has remained the same is the footprint of the
packages.
The basis of the pad design for surface mounted power MOSFET
is the basic footprint for the package. For the TSOP-6 package
outline drawing see http://www.vishay.com/doc?71200 and see
http://www.vishay.com/doc?72610 for the minimum pad footprint.
In converting the footprint to the pad set for a power MOSFET, you
must remember that not only do you want to make electrical
connection to the package, but you must made thermal connection
and provide a means to draw heat from the package, and move it
away from the package.
In the case of the TSOP-6 package, the electrical connections are
very simple. Pins 1, 2, 5, and 6 are the drain of the MOSFET and
are connected together. For a small signal device or integrated
circuit, typical connections would be made with traces that are
0.020 inches wide. Since the drain pins serve the additional
function of providing the thermal connection to the package, this
level of connection is inadequate. The total cross section of the
copper may be adequate to carry the current required for the
application, but it presents a large thermal impedance. Also, heat
spreads in a circular fashion from the heat source. In this case the
drain pins are the heat sources when looking at heat spread on the
PC board.
Since surface mounted packages are small, and reflow soldering
is the most common form of soldering for surface mount
components, “thermal” connections from the planar copper to the
pads have not been used. Even if additional planar copper area is
used, there should be no problems in the soldering process. The
actual solder connections are defined by the solder mask
openings. By combining the basic footprint with the copper plane
on the drain pins, the solder mask generation occurs automatically.
A final item to keep in mind is the width of the power traces. The
absolute minimum power trace width must be determined by the
amount of current it has to carry. For thermal reasons, this
minimum width should be at least 0.020 inches. The use of wide
traces connected to the drain plane provides a low impedance
path for heat to move away from the device.
REFLOW SOLDERING
Vishay Siliconix surface-mount packages meet solder reflow
reliability requirements. Devices are subjected to solder reflow as a
test preconditioning and are then reliability-tested using
temperature cycle, bias humidity, HAST, or pressure pot. The
solder reflow temperature profile used, and the temperatures and
time duration, are shown in Figures 2 and 3.
Figure 1 shows the copper spreading recommended footprint for
the TSOP-6 package. This pattern shows the starting point for
utilizing the board area available for the heat spreading copper. To
create this pattern, a plane of copper overlays the basic pattern on
pins 1,2,5, and 6. The copper plane connects the drain pins
electrically, but more importantly provides planar copper to draw
heat from the drain leads and start the process of spreading the
heat so it can be dissipated into the ambient air. Notice that the
planar copper is shaped like a “T” to move heat away from the
drain leads in all directions. This pattern uses all the available area
underneath the body for this purpose.

(Normalized)
A basic measure of a device’s thermal performance is the
junction-to-case thermal resistance, Rqjc, or the
junction-to-foot thermal resistance, Rqjf. 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 the thermal performance
of the TSOP-6.
