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. These

digital transistors are designed to replace a single device and its external resistor bias network.

The BRT eliminates these individual components by integrating them into a single device. In

the DWC3xx series, two BRT devices are housed in the SOT–363 package which is ideal

for low power surface mount applications where board space is at a premium.

• Simplifies Circuit Design

• Reduces Board Space

• Reduces Component Count

• We declare that the material of product compliance with RoHS requirements.
