The PQMD2Z application field and working principle is a transistors type of bipolar junction transistor array that is classified as pre-biased. This type of device is primarily designed to transfer an electrical signal from an input to an output with a certain level of linearity and voltage gain or attenuation. The PQMD2Z has two major components, the collector and the emitter, and can operate in a wide range of voltage and current requirements, while keeping its efficiency. The circuit requires two VCC power supplies with a voltage between 5.0 and 15.0 V to activate the metal-oxide-semiconductor field-effect transistor (MOSFET). Together with these two voltage supplies, two bipolar junction transistors (BJT) are integrated into the PQMD2Z design to provide additional current gain and protection in order to reduce the noise and other malfunctions.

The collector of the PQMD2Z is the portion of the device that receives the input signal. The collector is built up of two different segments, which are permanently connected to the two power supplies. This allows the collector to be powered from any pair of VCC values. The input signal is then coupled between the collector and the emitter. The current flows from the input of the PQMD2Z to the collector, where it is amplified or attenuated, depending on the design of the circuit. The output of the circuit is then routed through the emitter and can be used to power other devices or provide a control signal.

The emitter in the PQMD2Z circuit is not directly connected to the power supplies, although it receives its needed current from the collector. The emitter is also connected to a bias resistor to ensure that the current flows into the appropriate region of the circuit. When the PQMD2Z is powered, the electrical signal from the input is transferred from the collector to the emitter by means of the bias resistor. This resistor is actually a key component for controlling the power supply and the response time of the circuit. Without it, the internal components can be over-worked and eventually malfunction.

Additionally, the PQMD2Z circuit includes two protection diodes. This is an important feature since it prevents the circuit from becoming damaged due to an over-voltage situation. The diodes are connected in series with the circuit and they act as a safety measure to prevent the output signal from exceeding the recommended power levels. Thus, this feature protects the circuit in case of a high voltage surge or fluctuation.

The PQMD2Z application field and working principle is used in many applications due to its relatively small size and excellent performance. This type of transistor array is ideal for low voltage operations such as digital logic circuits, as well as signal amplifiers and signal detectors. Additionally, the pre-biased nature of the PQMD2Z design makes it suitable for many high speed operations and communications applications. This type of circuit is also used in motor and motor control applications, where precise control and operations are required.

In sum, the PQMD2Z application field and working principle is an important component to consider when designing circuits. Due to its pre-biased nature, it offers excellent performance and linearity in current and voltage transfer. This type of transistor array is also robust in terms of its power requirements, protection against over-voltage conditions and other situations, making it a dependable component in any type of electrical circuit design.
