A PUMB20.115 pre-biased array is a combination of two transistors in a single package. It consists of an NPN transistor and a PNP transistor mounted on one substrate, and is primarily used for audio amplifying applications. The NPN and PNP transistors are placed in close proximity to each other with their emitters connected to each other. This arrangement provides for an easy connection in the amplifier circuit, with each of the two transistor pairs as completing one circuit section.

The PUMB20.115 is most commonly used in audio amplifying systems because it provides an efficient circuit configuration, with a high-performance, low distortion rate. It is available in a wide range of amplifying formats, such as single-ended, class-A, or class-B big selections. This makes the PUMB20.115 an ideal device for a variety of amplifier designs.

The PUMB20.115 pre-biased array features two transistors and two emitter resistors integrated into the package. The two transistors are connected in parallel and the two emitter resistors are connected in series, with each transistor being connected to the center point of the emitter resistors. This arrangement allows the transistors to share the same current source and to optimize their performance, providing an efficient and high-performance power amplifier.

The PUMB20.115 pre-biased array also has some unique features that make it an attractive choice for a wide range of applications. The most notable is its low output impedance and high efficiency ratings. This is due to the integrated series connection of the two transistors, which prevents the transistor from being overstressed and allows for a higher operating current without increasing the power dissipation. In addition, the parallel circuit configuration substantially reduces the thermal and electrical losses, thus resulting in increased output power and energy efficiency.

The PUMB20.115 pre-biased array operates on an open-collector configuration, which means that the two transistors can be driven separately while still having the same current source connected. This results in higher efficiency ratings since a single transistor is used to drive each pair. In addition, this arrangement allows for better control over the output impedance, since the bias level is independent of the input signal level.

The PUMB20.115 pre-biased array also features a split-current mode, which allows for two complementary phase-shifted outputs. This can be used for higher power efficiency ratings, as well as for reducing noise and distortion. Additionally, the device is also capable of providing a symmetrical output with a low impedance level in the case of a single-ended amplifier.

In conclusion, the PUMB20.115 pre-biased array is an excellent choice for a variety of audio, consumer, and industrial applications due to its high efficiency, low output impedance, and flexible circuit configuration. It can be used in a wide variety of amplifying systems, from single-ended to class-B configurations, and is an attractive choice for many amplifier designs. The device is a reliable, cost-effective solution that provides high performance and excellent audio quality.
