The PEMD6,115 is a pre-biased array that has numerous useful applications and is comprised of two transistors. It functions as an oscillator and as a preamplifier in electronics equipment, and is popular in aviation and navigation systems. This article will discuss the applications of the PEMD6,115, its working principle, and why it is classified as one of the bipolar transistor array, pre-biased type.

The PEMD6,115 is a pre-biased npn/pnp array that consists of two transistors and several resistors in a small surface-mount package. It is designed to be used in various automotive electronics, from instrumentation to control lighting and air conditioning. The device’s small size makes it ideal for tight spaces and the reduced parts count increases reliability. Unlike a typical single-junction transistor, the PEMD6,115 allows the designer to create a low- cost and flexible two-transistor amplifier. This makes the device attractive for applications including audio equipment, power management, and mobile devices.

The PEMD6,115’s working principle is based on the fact that the capacitive loading of a single-transistor amplifier is lowered by the addition of a second transistor. In the device, both transistors are connected to the same source, allowing them to work in opposite directions. The resistive load connected to the emitters of the two transistors, biases the second transistor and allows the first transistor to enable and start oscillations. The biasing provides a certain amplitude and frequency for the oscillation, enabling the device to act as an oscillator and preamplifier.

The PEMD6,115 is classified as a type of ‘bipolar transistor array, pre-biased’ due to its structure and operation. As previously mentioned, the device consists of two transistors, each with its own emitter, that are connected to the same source. The added resistor between the two transistors’ emitters provides a bias voltage, which allows the device to work as an oscillator and preamplifier. This is why the PEMD6,115 is classified as a pre-biased array rather than just a simple bipolar transistor.

In conclusion, the PEMD6,115 is a pre-biased array consisting of two transistors that is used to amplify signal. It functions as an oscillator and preamplifier in numerous electronic applications, including automotive equipment, audio equipment, and power management. The device’s working principle is based on the fact that the capacitive loading of a single-transistor amplifier is lowered by the addition of a second transistor. The PEMD6,115 is classified as a type of ‘bipolar transistor array, pre-biased’ due to its structure and operation. Its small size, low parts count, and low cost make it an attractive option for many electronic projects.
