UMA4NT1, UMA6NT1 Preferred Devices Dual Common Emitter Bias Resistor Transistors PNP Silicon Surface Mount Transistors with Monolithic Bias Resistor Network http://onsemi.com 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 UMC2NT1 series, two BRT devices are housed in the SOT−353 package which is ideal for low power surface mount applications where board space is at a premium.
