SAFE OPERATING AREA
reliable operation, the stored energy from circuit inductance
dissipated in the transistor while in avalanche must be less
than the rated limit and adjusted for operating conditions
differing from those specified. Although industry practice is
to rate in terms of energy, avalanche energy capability is not
a constant. The energy rating decreases non–linearly with an
increase of peak current in avalanche and peak junction
temperature.
Although many E–FETs can withstand the stress of
drain–to–source avalanche at currents up to rated pulsed
current (IDM), the energy rating is specified at rated
continuous current (ID), in accordance with industry custom.
The energy rating must be derated for temperature as shown
in the accompanying graph (Figure 12). Maximum energy at
currents below rated continuous ID can safely be assumed to
equal the values indicated.
The Forward Biased Safe Operating Area curves define
the maximum simultaneous drain–to–source voltage and
drain current that a transistor can handle safely when it is
forward biased. Curves are based upon maximum peak
junction temperature and a case temperature (TC) of 25°C.
Peak repetitive pulsed power limits are determined by using
the thermal response data in conjunction with the procedures
discussed in AN569, “Transient Thermal Resistance –
General Data and Its Use.”
Switching between the off–state and the on–state may
traverse any load line provided neither rated peak current
(IDM) nor rated voltage (VDSS) is exceeded and the
transition time (tr,tf) do not exceed 10 µs. In addition the total
power averaged over a complete switching cycle must not
exceed (TJ(MAX) – TC)/(RθJC).
A Power MOSFET designated E–FET can be safely used
in switching circuits with unclamped inductive loads. For

SOLDER STENCIL GUIDELINES
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.
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
SC–59, SC–70/SOT–323, SOD–123, SOT–23, SOT–143,
SOT–223, SO–8, SO–14, SO–16, and SMB/SMC diode
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 D2PAK 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 15 shows a
typical stencil for the DPAK and D2PAK packages. The

SOLDERING PRECAUTIONS
• 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.
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.
* 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.

TYPICAL SOLDER HEATING PROFILE
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 joint.
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 16 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.
