This high voltage MOSFET uses an advanced termination scheme to  
provide enhanced voltage
−
blocking capability without degrading  
performance over time. In addition, this advanced TMOS E
−
FET is  
designed to withstand high energy in the avalanche and commutation  
modes. The new energy efficient design also offers a drain

to
−
source  
diode with a fast recovery time. Designed for high speed switching  
applications in power supplies, converters, PWM motor controls,
 
these  
devices are particularly well suited for bridge circuits where diode  
speed and commutating safe operating areas are critical and offer  
additional safety margin against unexpected voltage transients.

POWER MOSFET SWITCHING

Switching behavior is most easily modeled and predicted  
by recognizing that the power MOSFET is charge  
controlled. The lengths of various switching intervals (

are determined by how fast the FET input capacitance can

.
At high switching speeds, parasitic circuit elements  
complicate the analysis. The inductance of the MOSFET  
source lead, inside the package and in the circuit wiring  
which is common to both the drain and gate current paths,  
produces a voltage at the source which reduces the gate  
drive current. The voltage is determined by Ldi/dt, but since  
di/dt is a function of drain current, the mathematical solution  
is complex. The MOSFET output capacitance also  
complicates the mathematics. And finally, MOSFE

finite internal gate resistance which effectively adds to the  
resistance of the driving source, but the internal resistance  
is difficult to measure and, consequently, is not specified.  
The resistive switching time variation versus gate  
resistance (Figure
 
9) shows how typical switching  
performance is affected by the parasitic circuit elements.
 
If  
the parasitics were not present, the slope of the curves  
would maintain a value of unity regardless of the switching  
speed. The
 
circuit used to obtain the data is constructed to  
minimize common inductance in the drain and gate circuit  
loops and is believed readily achievable with board  
mounted components.
 
Most power electronic loads are  
inductive; the data in the figure is taken with a resistive load,  
which approximates an optimally snubbed inductive load.  
Power MOSFE

load; however, snubbing reduces switching losses.  
The published capacitance data is difficult to use for  
calculating rise and fall because drain

gate capacitance  
varies greatly with applied voltage. Accordingly, gate  
charge data is used.
 
In most cases, a satisfactory estimate  
of average input current (I

) can be made from a  
rudimentary analysis of the drive circuit so that  
t = Q/I

INFORMATION FOR USING THE DPAK SURFACE MOUNT PACKAGE  
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.

These 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 T

junction temperature of the die, R

other alternatives to achieving higher power dissipation from  
the surface mount packages. One is to increase the area of

power dissipation can be increased. Although one can  
Another alternative would be to use a ceramic substrate or

SOLDER STENCIL GUIDELINES  
Prior to placing surface mount components onto a printed  
circuit board, solder paste must be applied to the pads.  
Solder stencils are used to screen the optimum amount.  
These stencils are typically 0.008 inches thick and may be  
made of brass or stainless steel. For packages such as the

packages, the stencil opening should be the same as the pad  
size or a 1:1 registration. This is not the case with the DPAK  
and D

2

PAK packages. If one uses a 1:1 opening to screen  
solder onto the drain pad, misalignment and/or  
“tombstoning” may occur due to an excess of solder. For  
these two packages, the opening in the stencil for the paste  
should be approximately 50% of the tab area. The opening  
for the leads is still a 1:1 registration. Figure 16 shows a  
typical stencil for the DPAK and D

2

PAK packages. The  
pattern of the opening in the stencil for the drain pad is not  
critical as long as it allows approximately 50% of the pad to  
be covered with paste.

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 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.  
•
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 10 seconds.  
* 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 D

PAK  
is not recommended for wave soldering.

TYPICAL SOLDER HEATING PROFILE  
For any given circuit board, there will be a group of control  
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 17
7
−
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.  
settings that will give the desired heat pattern. The operator  
must set temperatures for several heating zones, and a  
figure for belt speed.
T
a
ken 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 17 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
