The DMA964020R is a pre-biased quad array bipolar junction transistor (BJT) that offers big benefits to its users. With its high frequency performance, as well its excellentCurrent gain, the chip is ideal for a variety of applications.

Application Field

The DMA964020R can be used in a variety of settings, including in analog circuits, linear circuits, and RF applications. The chip is capable of working with frequencies up to 1GHz, and it is highly reliable, making it ideal for high frequency applications. The chip can also be used in high current applications, as it has a current gain of 200-400, allowing significant amounts of current to be passed through the chip.

The chip also offers reliable on-state characteristics, which makes it a great choice for power converters and switching circuits. The low offset voltage and the low in-line power rating helps to reduce power losses and make the chip highly energy efficient and cost effective.

Working Principle

The quad array on the DMA964020R is made up of four independent transistors, each having an independent base and collector. The transistors are connected in such a way that it greatly reduces the effect of thermal resistance, increasing the reliability and stability of the chip. Additionally, the transistors are pre-biased, meaning that the collector and base junctions are set up correctly prior to the insertion of the chip into the circuit. This eliminates the need for the user to have to adjust the bias levels.

The chip works by using the controlled collector current from the base voltage. This current is amplified by the transistor and is passed to the collector as a larger current. This, in turn, can then be used as a voltage in the circuit. The transistor has a high current gain, meaning that it can amplify a small current into a larger current, allowing it to act as a switch and control power to the circuit.

Conclusion

The DMA964020R provides a range of advantages for its users, such as high frequency performance, excellent current gain and reliable on-state characteristics. It is ideal for analog and RF applications, as well as for power converters and switching circuits. The chip is highly energy efficient, and the quads are pre-biased, which eliminates the need for the user to adjust the bias levels.
