Preferred Devices
Bias Resistor Transistors
PNP Silicon Surface Mount Transistors
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.

BIAS RESISTOR
TRANSISTORS
• 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
