The ADA114YUQ-13 pre-biased transistor array is a unique offering from Analog Devices that fits into the category of transistors – bipolar (BJT) – arrays, pre-biased. Its unique features include capacitively-biased outputs, and an integrated Schottky diode array for EMI protection. This transistor array is designed for automotive, industrial and consumer applications, and is suitable for use in DC-to-DC and frequency conversion sections of electronic applications, as well as junction field-effect transistors (JFETs).

The ADA114YUQ-13 is a monolithic integrated package of four N-type (NPN) transistors. It is designed to provide robust performance and high current handling capability with low power dissipation. Each transistor of the array consists of two transistor cells, with each having two emitters, two collectors and a single base terminal. The transistors are connected in a common collector configuration. This configuration enables a dynamic biasing of the transistors which is accomplished by the use of an internal capacitance and an external resistor.

In the common collector configuration, the ADC114YUQ-13 utilizes the capacitively-biased outputs to provide both high current handling capabilities as well as low power dissipation. The capacitors are used to generate a bias voltage on the collectors of the transistor cells, while the resistor keeps the transistors out of saturation. The resulting low current transfers provide small switching times and minimized input noise, while at the same time providing high current gains and low driving voltages. Additionally, the integrated Schottky diode array helps to protect the transistors from EMI, and contributes to its overall robustness.

The ADC114YUQ-13 has a wide range of operating temperature, from -40 to +125 °C, making it suitable for use in automotive and industrial applications. The ADA114YUQ-13 also has an excellent thermal resistance of 0.6°C/W. It is capable of handling high current peaks of up to 350mA and power dissipation of up to 2 W, while still providing excellent high frequency switching characteristics.

The ADC114YUQ-13 pre-biased transistor array provides a unique solution for a number of applications. Its wide range of temperature and high current capabilities make it well-suited for automotive and industrial applications, while its low power dissipation and integrated Schottky diode array allow for the development of robust and effective frequency conversion circuits for consumer applications. Furthermore, its capacitively-biased outputs provide an ideal low-noise, low-power solution for a variety of DC-to-DC and frequency conversion designs.
