The PUMD19,115 is a pre-biased bipolar array in the form of a Darlington connected configuration. It is a popular choice for use in analog circuits, audio amplifiers and switching circuits, offering superior performance over other types of bipolar configurations. This article will discuss the application field and working principle of the PUMD19,115.

Application

The PUMD19,115 is most commonly used in analog circuits and audio amplifiers. It is also used in power switching circuits such as those used in power supplies and battery charging. Another application field is motor control, where the PUMD19,115 can be used in a voltage regulator to control the speed and direction of a motor.

The PUMD19,115 is also used in automotive applications such as the control of the spark advance in ignition systems. It is also used in medical diagnostic equipment and medical robots. The PUMD19,115 is also used in photovoltaic cells as a current-limiting element.

Working Principle

The PUMD19,115 is a Darlington connected configuration and consists of two bipolar transistors connected in series. The first transistor is the input or ‘driving’ transistor and the second transistor is the output or ‘driven’ transistor.

The input transistor receives a small input voltage and amplifies it to a larger voltage, providing a voltage gain. This amplified voltage is then applied to the base of the output transistor. The output transistor amplifies this voltage further and produces an amplified output voltage.

The PUMD19,115 is pre-biased, meaning it is ready to use without any additional components. This saves time and money, as there is no need to manually bias the transistors. In addition, since the transistors are connected in series, the gain of the output is greater than if the transistors were connected in parallel.

Benefits

The PUMD19,115 offers several benefits over other types of bipolar configurations. Compared to the conventional transistor configuration, the Darlington configuration offers a 40-50% higher voltage gain. In addition, the pre-biased transistors require no additional components, making it ideal for applications where space is a factor.

The PUMD19,115 also offers minimal power consumption and low distortion. This makes it a great choice for audio applications. Additionally, the PUMD19,115 is extremely stable and reliable, making it well suited for automotive applications where long-term reliability is important.

Conclusion

The PUMD19,115 is a popular pre-biased bipolar array in the form of a Darlington configuration. It is most commonly used in analog circuits, audio amplifiers, and power switching circuits. It is pre-biased, meaning no additional components are required for operation. The PUMD19,115 offers a higher voltage gain than other configurations, as well as minimal power consumption and low distortion. Finally, the PUMD19,115 is extremely stable and reliable, making it the ideal choice for automotive applications.
