DTA143ZKA-TP

The DTA143ZKA-TP is a single, pre-biased bipolar transistor specifically designed to deliver outstanding performance in small- and medium-power applications. The device is a self-contained integrated circuit that incorporates a resistor and a transistor into one structure, eliminating the need to have external components to create a bias voltage or current. The device offers cost savings due to its simple construction and intuitive usage. In addition, its thermal characteristics offer excellent stability in a wide ambient temperature range.

The DTA143ZKA-TP is a high-voltage, high-current device, capable of handling a maximum collector-emitter voltage of 600V, and a continuous collector current of 7 A. It is designed to provide up to 1.5 W of power in a surface-mountable 4-pin package. It is suitable for most applications in television and radio systems, as well as other consumer electronics. It is also suitable for applications in discrete-segment, linear and unbuffered logic.

The DTA143ZKA-TP is built around a depletion-mode, silicon NPN transistor. This type of transistor is characterized by a normally ON switch, which means that when there is no base control current, the collector-emitter voltage is equal to the substrate voltage. The device has an integrated resistor between the collector and the base legs which ensures a reverse-gate voltage is maintained and emitter current stability.

The DTA143ZKA-TP operates with a base-emitter voltage of approximately 6.5 V, which is set by the integrated resistor. The resistor also ensures a collector-emitter voltage drop of 6 V. The device also has a thermal cutoff feature which prevent device overheating by monitoring the collector-emitter voltage and automatically shutting off power when a certain threshold is exceeded.

The DTA143ZKA-TP is well-suited for use in applications such as power switching systems, linear and logic circuits, HVAC, etc. It allows for the creation of high voltage, high current connections in a cost-effective, efficient way. It can serve as a reliable, robust, and cost-effective solution for applications using non-isolated MOSFETs, as well as applications requiring junction insulation. Its integrated resistor also simplifies circuit design and minimizes the number of components needed.

The DTA143ZKA-TP is an ideal choice for applications requiring high voltage, high current switches. Its built-in thermal cutoff feature ensures reliable operation and its integrated resistor greatly simplifies circuit design. With its high current capacity and excellent thermal characteristics, the DTA143ZKA-TP can serve as a highly effective, reliable, and cost-effective solution for numerous applications.
