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-89 package
which is designed for low power surface mount applications.
• Simplifies Circuit Design
• Reduces Board Space
• Reduces Component Count
• The SC-89 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.
• We declare that the material of product compliance with
RoHS requirements.

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
