Built-in Resistors Transistor
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 SMUN5211DW 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
• Pb-Free Package is available
