The Dual PNP Bipolar Digital 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 Dual PNP Bipolar Digital Transistor eliminates these individual components by integrating them into a single device. In the UMC2NT1 series, two devices are housed in the SOT-353 package which is ideal for low power surface mount applications where board space is at a premium.
