Bias Resistor Transistor
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 SOT-23 package which is
designed for low power surface mount applications.
• Simplifies Circuit Design
• Reduces Board Space
• Reduces Component Count
PIN 3
COLLECTOR
(OUTPUT)
• The SOT-23 package can be soldered using wave or
reflow. The modified gull-winged leads absorb thermal
R1
stress during soldering eliminating the possibility of PIN 1 R2
damage to the die.
BASE
• Available in 8 mm embossed tape and reel. Use the (INPUT)
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.
