PNP 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–70/SOT–323 package which
is designed for low power surface mount applications.
Simplifies Circuit Design
Reduces Board Space
Reduces Component Count
The SC–70/SOT–323 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 embossed tape and reel
Use the Device Number to order the 7 inch/3000 unit reel.
Replace “T1” with “T3” in the Device Number to order
the 13 inch/10,000 unit reel.
