Motorola Small–Signal Transistors, FETs and Diodes Device Data
NPN and PNP Silicon Surface Mount Transistors
with Monolithic Bias Resistor 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. 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
MUN5311DW1T1 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
• Available in 8 mm, 7 inch/3000 Unit Tape and Reel.
