These Power MOSFET devices 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.

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 (
∆
t)  
are determined by how fast the FET input capacitance can  
be charged by current from the generator.  
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  
The capacitance (C
 
) is read from the capacitance curve at  
a voltage corresponding to the off−state condition when  
iss

and is read at a voltage corresponding to the  
d(on)  
on−state when calculating t  
.
d(off)  
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, MOSFETs have  
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
 
11) 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.

DRAIN−TO−SOURCE DIODE CHARACTERISTICS  
The switching characteristics of a MOSFET body diode  
are very important in systems using it as a freewheeling or  
commutating diode. Of particular interest are the reverse  
recovery characteristics which play a major role in  
determining switching losses, radiated noise, EMI and RFI.  
System switching losses are largely due to the nature of  
the body diode itself. The body diode is a minority carrier  
high di/dts. The diode’s negative di/dt during t
 
is directly  
controlled by the device clearing the stored charge.  
a
However, the positive di/dt during t
 
is an uncontrollable

diode characteristic and is usually the culprit that induces  
current ringing. Therefore, when comparing diodes, the  
ratio of t

as a good indicator of recovery

to the storage of minority carrier charge, Q
 
, as shown in  
RR  
the typical reverse recovery wave form of Figure 13. It is this  
stored charge that, when cleared from the diode, passes  
through a potential and defines an energy loss. Obviously,  
repeatedly forcing the diode through reverse recovery  
further increases switching losses. Therefore, one would

the high cell density diode means they can be forced through  
reverse recovery at a higher di/dt than a standard cell

from switching the diode will be less due to the shorter

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  
into the equation for an ambient temperature T
 
of 25
°
C,  
one can calculate the power dissipation of the device which  
in this case is 0.78 Watts.

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 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  
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 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.  
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 18 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
