DDTC123TUA-7

Transistors - Bipolar (BJT) - Single, Pre-Biased

The DDTC123TUA-7 transistor is a single pre-biased BJT that is designed for use in a wide range of applications. This transistor is rated for a low voltage of 0.4V and a high voltage of 1.4V. It has an Ultra-low threshold voltage of only 0.7V and is suitable for low voltage operation. The DDTC123TUA-7 has a PNP configuration, meaning it is positively biased in the collector-base region and, in the absence of an applied signal, will be turned on.

The DDTC123TUA-7 is useful for a variety of applications such as field-effect transistors (FETs), voltage regulators, DC-DC converters, switching power supplies, current sensor circuits, and pulse-width modulation (PWM) control. It is also suitable for use in low power amplifiers, as well as in audio amplifiers and motor driver circuits. Additionally, it can be used for general purpose amplifying and switching applications.

The working principle of the DDTC123TUA-7 transistor is based on the PNP configuration. This means that it relies on two parts, namely a collector and an emitter. The collector is negatively charged and drives current across the base-emitter junction. Initially, the electrons are injected into the base and these then flow out of the emitter, creating a current and resulting in a voltage drop across the collector and emitter. This voltage drop is the working voltage of the transistor.

The functioning of the DDTC123TUA-7 relies on the collector and emitter voltages. When a voltage is applied to the base, the electrons from the collector flow into the base, where they are then emitted from the emitter. The resulting current flow from the collector to the emitter forms a voltage drop, and this voltage drop is the working voltage of the transistor. The current flow within the transistor is regulated by the value of the base voltage.

The DDTC123TUA-7 transistor is ideal for applications requiring a low voltage operation and low-power operation, such as amplifiers, FETs, switching power supplies, and other control circuits. Its low threshold voltage and ultra-low power consumption make it suitable for these types of applications. Furthermore, its high voltage rating and collector-emitter saturation voltage make it ideal for transistor projects that require a relatively high voltage.
