Transistors are an important class of electronic devices used to amplify and switch a signal. Bipolar transistors, or BJTs, are a type of transistor in which two p-type and one n-type semiconductor regions are connected together. Arrays of BJTs, called pre-biased transistors, are used in many applications. The PUMH2/DG/B3,115 is a pre-biased bipolar transistor array used in applications requiring low power consumption and high input/output voltage ratings.

The PUMH2/DG/B3,115 consists of three identical NPN transistors, each with an area of 2.3 mm² (0.093 in²). The chip is designed with an output voltage range of -41.5 V to +50 V. It has a maximum current rating of 2 A and an output power of 60 mW. The PUMH2/DG/B3,115 is rated as having a gain of 20 dB.The PUMH2/DG/B3,115 is typically used in applications requiring high-speed, low power consumption and high input/output voltage ratings. It has been used in applications such as switching and interface circuits, driver stages, sample and hold circuits, audio amplifier stages, and motor control circuits.The PUMH2/DG/B3,115 operates using a common emitter configuration. This configuration uses a single current source to drive two sets of emitters, which in turn drive the bases of the two transistors. The common emitter configuration has the advantage of allowing a higher output voltage with a lower power rating than other configurations such as common base.In operation, the bases of the two transistors are biased positively, allowing current to flow through the transistors and into the collector. As current flows through the active region of the transistor, it produces a gain. This gain is the signal which is output from the PUMH2/DG/B3,115. The gain is detailed in the transistor\'s data sheet, with higher gains achieved at higher power ratings.The PUMH2/DG/B3,115 is rated for operating temperatures of -40 °C to 125 °C. It is also rated to withstand an avalanche energy of over 200 mJ at 25 °C. The package includes an internal insulation resistance of at least 1000 MΩ, with a leakage current of 0.1 μA at maximum bias.The PUMH2/DG/B3,115 is an excellent example of a pre-biased bipolar transistor array. It is capable of providing cost-effective, low power solutions for applications requiring high input/output voltage ratings. With its high input/output voltage ratings, high gain, and low power requirements, it is well suited to applications such as audio amplifiers, motor control circuits and interface circuits.
