Medium Power Surface Mount Products
Motorola Preferred Device
Micro8 devices are an advanced series of power MOSFETs
which utilize Motorola’s High Cell Density HDTMOS process to
achieve lowest possible on–resistance per silicon area. They are
capable of withstanding high energy in the avalanche and commutation modes and the drain–to–source diode has a very low reverse
recovery time. Micro8 devices are designed for use in low voltage,
high speed switching applications where power efficiency is important.
Typical applications are dc–dc converters, and power management in
portable and battery powered products such as computers, printers,
cellular and cordless phones. They can also be used for low voltage
motor controls in mass storage products such as disk drives and tape
drives. The avalanche energy is specified to eliminate the guesswork
in designs where inductive loads are switched and offer additional
safety margin against unexpected voltage transients.

INFORMATION FOR USING THE Micro8 SURFACE MOUNT PACKAGE
MINIMUM RECOMMENDED FOOTPRINT FOR SURFACE MOUNTED APPLICATIONS
Surface mount board layout is a critical portion of the total
design. The footprint for the semiconductor packages must be
the correct size to ensure proper solder connection interface
between the board and the package. With the correct pad
geometry, the packages will self–align when subjected to a
solder reflow process.

Micro8 POWER DISSIPATION
The power dissipation of the Micro8 is a function of the input
pad size. This can vary from the minimum pad size for
soldering to the pad size given for maximum power
dissipation. Power dissipation for a surface mount device is
determined by TJ(max), the maximum rated junction
temperature of the die, RθJA, the thermal resistance from the
device junction to ambient; and the operating temperature, TA.
Using the values provided on the data sheet for the Micro8
package, PD can be calculated as follows:
PD =
TJ(max) – TA
RθJA
The values for the equation are found in the maximum
ratings table on the data sheet. Substituting these values into
the equation for an ambient temperature TA of 25°C, one can
calculate the power dissipation of the device which in this case
is 0.78 Watts.
PD = 150°C – 25°C = 0.78 Watts
160°C/W
The 160°C/W for the Micro8 package assumes the
recommended footprint on a glass epoxy printed circuit board
to achieve a power dissipation of 0.78 Watts using the footprint
shown. Another alternative would be to use a ceramic
substrate or an aluminum core board such as Thermal Clad.
Using board material such as Thermal Clad, the power
dissipation can be doubled using the same footprint.
SOLDERING PRECAUTIONS
The melting temperature of solder is higher than the rated
temperature of the device. When the entire device is heated
to a high temperature, failure to complete soldering within a
short time could result in device failure. Therefore, the
following items should always be observed in order to
minimize the thermal stress to which the devices are
subjected.
• Always preheat the device.
• The delta temperature between the preheat and soldering
should be 100°C or less.*
• When preheating and soldering, the temperature of the
leads and the case must not exceed the maximum
temperature ratings as shown on the data sheet. When
using infrared heating with the reflow soldering method,
the difference shall be a maximum of 10°C.
4
• The soldering temperature and time shall not exceed
260°C for more than 10 seconds.
• When shifting from preheating to soldering, the maximum
temperature gradient shall be 5°C or less.
• After soldering has been completed, the device should be
allowed to cool naturally for at least three minutes.
Gradual cooling should be used as the use of forced
cooling will increase the temperature gradient and result
in latent failure due to mechanical stress.
• Mechanical stress or shock should not be applied during
cooling.
* Soldering a device without preheating can cause excessive
thermal shock and stress which can result in damage to the
device.

TYPICAL SOLDER HEATING PROFILE
For any given circuit board, there will be a group of control
settings that will give the desired heat pattern. The operator
must set temperatures for several heating zones and a figure
for belt speed. Taken together, these control settings make up
a heating “profile” for that particular circuit board. On
machines controlled by a computer, the computer remembers
these profiles from one operating session to the next. Figure
3 shows a typical heating profile for use when soldering a
surface mount device to a printed circuit board. This profile will
vary among soldering systems, but it is a good starting point.
Factors that can affect the profile include the type of soldering
system in use, density and types of components on the board,
type of solder used, and the type of board or substrate material
being used. This profile shows temperature versus time. The

line on the graph shows the actual temperature that might be
experienced on the surface of a test board at or near a central
solder joint. The two profiles are based on a high density and
a low density board. The Vitronics SMD310 convection/infrared reflow soldering system was used to generate this
profile. The type of solder used was 62/36/2 Tin Lead Silver
with a melting point between 177 –189°C. When this type of
furnace is used for solder reflow work, the circuit boards and
solder joints tend to heat first. The components on the board
are then heated by conduction. The circuit board, because it
has a large surface area, absorbs the thermal energy more
efficiently, then distributes this energy to the components.
Because of this effect, the main body of a component may be
up to 30 degrees cooler than the adjacent solder joints.
