NPN and PNP Silicon Surface Mount
Transistors with Monolithic Bias
Resistor 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. These digital transistors are
designed to replace a single device and its external resistor bias
network. The BRT eliminates these individual components by
integrating them into a single device. In the EMD5DXV6T1 series,
two complementary BRT devices are housed in the SOT−563 package
which is ideal for low power surface mount applications where board
space is at a premium.

INFORMATION FOR USING THE SOT−563 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 insure proper solder connection

SOT−563 POWER DISSIPATION
The power dissipation of the SOT−563 is a function of
the 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 T
of the die, R
, the maximum rated junction temperature
J(max)
, the thermal resistance from the device
JA
junction to ambient, and the operating temperature, TA. Using the values provided on the data sheet for the SOT−563
package, PD can be calculated as follows:
PD =

− T
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
of 25°C,
A
one can calculate the power dissipation of the device which
in this case is 150 milliwatts.
150°C − 25°C
PD =
833°C/W
= 150 milliwatts
The 833°C/W for the SOT−563 package assumes the use
of the recommended footprint on a glass epoxy printed circuit board to achieve a power dissipation of 150 milliwatts.
There are other alternatives to achieving higher power dissipation from the SOT−563 package. 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, an aluminum core board, the power dissipation can be doubled 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 solder-
ing 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 maxi-
mum 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 dur-
ing cooling.
* Soldering a device without preheating can cause excessive thermal shock and stress which can result in damage
to the device.
