LMUN5311DW1T1
Series
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 tran-
sistors 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
LMUN5311DW1T1 series, two complementary 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
