MURB1620CT INFORMATION FOR USING THE D2PAK SURFACE MOUNT PACKAGE
MINIMUM RECOMMENDED FOOTPRINT FOR SURFACE MOUNTED APPLICATIONS Surface mount board layout is a critical portion of the interface between the board and the package. With the total design. The footprint for the semiconductor packages correct pad geometry, the packages will self align when must be the correct size to insure proper solder connection 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, RJA, 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 RJA
into the equation for an ambient temperature TA of 25C, one can calculate the power dissipation of the device which in this case is 3.0 watts.
PD = 175C - 25C = 3.0 watts 50C/W
The values for the equation are found in the maximum ratings table on the data sheet. Substituting these values
The 50C/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 3.0 watts using the footprint shown. Another alternative is to use a ceramic substrate or an aluminum core board such as Thermal CladTM. 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 100C 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 10C. * The soldering temperature and time shall not exceed 260C for more than 5 seconds. * When shifting from preheating to soldering, the maximum temperature gradient shall be 5C 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 7 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.
