INFORMATION FOR USING THE D2PAK SURFACE MOUNT PACKAGE

MINIMUM RECOMMENDED FOOTPRINTS 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 insure 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.

D2PAK POWER DISSIPATION

The power dissipation of the D2PAK is a function of the

drain pad size. This can vary from the minimum pad size

for soldering to a 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 D2PAK 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 2.5 watts.

PD = 150°C - 25°C= 2.5 watts

50°C/W

The 50°C/W for the D2PAK package assumes the

recommended drain pad area of 158K mil2 on FR-4 glass

epoxy printed circuit board to achieve a power dissipation

of 2.5 watts using the footprint shown. Another alternative

is to use a ceramic substrate or an aluminum core board

such as Thermal Clad. By using an aluminum core board

material such as Thermal Clad, the power dissipation can

be doubled using the same footprint.

GENERAL 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.

•The soldering temperature and time shall not exceed

260°C for more than 5 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.

* * Due to shadowing and the inability to set the wave

height to incorporate other surface mount components, the

D2PAK is not recommended for wave soldering.

RECOMMENDED PROFILE FOR REFLOW SOLDERING

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 5 shows a typical heating profile

for use when soldering the D2PAK 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.
