Application Field

The ULQ2001D1013TR NPN transistor array is used in various applications from communication receivers, mobile communication systems, and interfacing to analog-to-digital or digital-to-analog converters, among other applications. It can also be used in the DSP, A/D and D/A circuits, and the power amplifier/buffer circuitry in electronic devices. Furthermore, it is also applicable in applications such as high-frequency circuits, industrial automation control circuits, and automotive systems.

Working Principle

The ULQ2001D1013TR transistor array works by controlling the flow of current through emitter-base junctions and by controlling the current gain of each transistor in the array. When voltage is applied to the base electrodes of the transistors, the base current combines with the collector current to create a current gain, which is defined by the current amplification factor (β). This beta value can be varied by adjusting the base-emitter voltage, which in turn changes the current gain of each transistor in the array.

The current gain in each transistor can further be increased by increasing the collector-emitter voltage. By connecting the collector-emmitter junction with other components, such as resistors or capacitors, the current gain can be adjusted by controlling the combined resistances or capacitances. This allows for increased control over the current gain in each transistor.

The ULQ2001D1013TR is also capable of providing a base current limit of up to several watts per transistor, and can be configured with dual collectors, enabling the transistor array to be used in high-current applications. In addition, the ULQ2001D1013TR features a DC current gain of up to 400 and a low noise figure, making it ideal for high-performance analog and digital applications.

The ULQ2001D1013TR also features reverse voltage protection and internal ESD protection, allowing for multiple transistors in a single package with better current performance and protection from power surges and other environmental factors. Additionally, the ULQ2001D1013TR has an operating temperature range from -40°C to +85°C, making it suitable for use in thermally demanding applications.
