Bias Resistor Transistor
NPN Silicon Surface Mount Transistor
with Monolithic Bias Resistor Network
This new series of digital transistors is designed to replace a single
device and its external resistor bias network. The BRT (Bias Resistor
Transistor) contains a single transistor with a monolithic bias network
consisting of two resistors; a series base resistor and a base–emitter
resistor. The BRT eliminates these individual components by
integrating them into a single device. The use of a BRT can reduce
both system cost and board space. The device is housed in the
SC–75/SOT–416 package which is designed for low power surface
mount applications.
• Simplifies Circuit Design
• Reduces Board Space
• Reduces Component Count
• The SC–75/SOT–416 package can be soldered using
wave or reflow. The modified gull–winged leads absorb
thermal stress during soldering eliminating the possibility
of damage to the die.
• Available in 8 mm, 7 inch/3000 Unit Tape & Reel

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.

Unit: mm
SOT–416/SC–75 POWER DISSIPATION
The power dissipation of the SOT–416/SC–75 is a
function of the 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 determined by T
J(max)
, the maximum rated
junction temperature of the die, R
θ
JA
, the thermal
resistance from the device junction to ambient; and the
operating temperature, TA. Using the values provided on
the data sheet, P
D
can be calculated as follows:
PD =
T
J(max)
– T
A
R
θ
JA
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 T
A
of 25°C,
one can calculate the power dissipation of the device which
in this case is 200 milliwatts.
PD =
150°C – 25°C
= 200 milliwatts
600°C/W
The 600°C/W assumes the use of the recommended
footprint on a glass epoxy printed circuit board to achieve a
power dissipation of 200 milliwatts. Another alternative
would be to use a ceramic substrate or an aluminum core
board such as Thermal Clad. Using a board material such
as Thermal Clad, a higher power dissipation can be
achieved using the same footprint.
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 should be a maximum of 10°C.
• The soldering temperature and time should not exceed
260°C for more than 10 seconds.
• When shifting from preheating to soldering, the
maximum temperature gradient should 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.

SOLDER STENCIL GUIDELINES
Prior to placing surface mount components onto a printed
circuit board, solder paste must be applied to the pads. A
solder stencil is required to screen the optimum amount of
solder paste onto the footprint. The stencil is made of brass
or stainless steel with a typical thickness of 0.008 inches.
The stencil opening size for the surface mounted package
should be the same as the pad size on the printed circuit
board, i.e., a 1:1 registration.
TYPICAL SOLDER HEATING PROFILE
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 26 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 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.
