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.
• Pb-Free Package is Available.
