Dual Bias Resistor Transistors
NPN and PNP Silicon Surface Mount Transistors with Monolithic Bias Resistor Network
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 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 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
