The PUMH9/165 are special arrays that are designed for bipolar transistors and circuits in general. These arrays are also known as pre-biased arrays, as each individual transistor is held in a balanced forward bias state, ready to be switched on when required. This makes them ideal for applications such as audio amplification, RF, and power control circuits in the Industrial, Automotive, Telecommunications and Consumer markets.

The PUMH9/165 works by combining several transistors together to form an integrated circuit, with each transistor typically providing 0.4 A of current and a VCE of up to 6 V. The PUMH9/166 also includes an integrated DC voltage regulator, which ensures a uniform current, matching the characteristics of the source circuit when the transistors are in operation. This makes them suitable for use in a broad range of applications, from automotive engines and air conditioning systems to audio systems, cell phones and medical devices.

The ideal application for the PUMH9/165 is in a closed-loop, digital control environment where speed and accuracy are paramount. This can include such things as digital amplifier, AD/DA converters, high-speed imaging devices and control systems. Due to the pre-bias, the PUMH9/165 can easily provide a stable output signal, and can effectively combine with an analog circuit, especially in applications such as power amplifiers, filters, and audio systems. The integrated DC voltage regulator is another strong point of the PUMH9/165, as it enables the system to accurately control the transistor\'s voltage, ensuring a reliable output.

The working principle of the PUMH9/165 can be summarized as follows: each individual transistor is held in a balanced forward bias, ready to be switched on when required. The individual transistors are contained within a single integrated circuit, and the DC voltage regulator ensures a uniform current flow when the transistors are in operation. The integrated circuit also provides protection from overvoltage, electromagnetic interference and thermal overload.

Given the number of advantages that the PUMH9/165 offers, this integrated circuit can be used in a wide variety of applications. From digital control systems for automotive engines and audio systems to medical devices and high-speed imaging devices, this integrated circuit can provide a reliable and stable output that is highly dependent on the quality of components and installation. Therefore, it is essential that the PUMH9/165 is installed correctly and maintained properly in order to ensure optimal performance.
