Resistor Network
The Bias Resistor Transistor (BRT) 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 NSB4904DW1T1G and
NSB4904DW1T2G, two complementary BRT devices are housed in
the SC−88/SOT−363 package which is ideal for low power surface
mount applications where board space is at a premium.

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
