ZXT12P20DXTA Discrete Semiconductor Products

The ZXT12P20DXTA is a transistor array used in a variety of applications, such as signal conditioning and power management. It is a bipolar (BJT) transistor array with two individual bipolar transistors in a single package. The package consists of two NPN transistors connected in a Darlington configuration, where the base of each NPN transistor is connected to the collector of the other. The gate voltage signal is applied to the common base of both transistors, and the output current is taken from the common collector. It is mainly used in signal conditioning and power management applications.

The ZXT12P20DXTA offers a wide range of device features and performance levels. These features include low on-state resistance and high output current capabilities, as well as an integrated thermal protection feature. It has a maximum quiescent current of 4mA, and a maximum peak current of up to 20 A. It is also able to operate at temperatures ranging from -40 to +110° C.

The ZXT12P20DXTA also has two operating modes. The first is the half-bridge mode, in which only one transistor is switched on at a time. This mode is useful for low-power applications, such as battery-powered devices. The second mode is the full-bridge mode, in which both transistors are switched on simultaneously. This mode is useful for high-power applications, such as switching power supplies.

The working principle of the ZXT12P20DXTA transistor array is relatively simple. The gate voltage (Vg) is applied to the common base of both transistors. This voltage controls the current flow through the emitter-collector junction. The current through the collector-emitter junction is controlled by the amount of current flowing through each transistor. When the transistors are in the full-bridge mode, both transistors are turned on simultaneously and the total output current is equal to the sum of the individual transistor currents. In the half-bridge mode, only one transistor is turned on at a time and the output current is equal to the current of that single transistor.

The ZXT12P20DXTA transistor array is used in a variety of applications in the fields of signal conditioning and power management. It is especially useful for applications that require a high output current and low on-state resistance, such as switching power supplies and motor control circuits. Its thermal protection feature provides additional protection against thermal overloads, making it an ideal choice for applications where high power and reliability are important.
