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.
