The forward breakdown voltage and the collector-emitter leakage current are both needed to determine how best to level up and down this device. The PDTA143ZT,235 has a collector-emitter breakdown voltage of 5V, a leakage current of 40 mA, and a saturation voltage of 1.2V. In addition, the device has a typical turn-on delay of 20ns, and a rise time of 10 ns.

Applications

The PDTA143ZT,235 functionally combines switching, amplification, and selectivity. This makes it suited for a variety of applications, such as power supply systems, audio amplifiers, and current switching applications. The PDTA143ZT,235 offers stable performance when used at high frequency, and can be used to regulate output currents from low to medium levels. Its pre-biased collector voltage limits current to threshold levels, thereby allowing for greater control of power delivery and energy efficiency.

Working Principle

The PDTA143ZT,235 utilizes the principle of a Bipolar Junction Transistor (BJT). At the most basic level, a BJT is an active three-terminal semiconductor device in which current flows between two resistors. The PDTA143ZT,235 consists of three terminals, namely the emitter, the collector, and the base. The emitter is the input where the voltage is applied, and the collector is the output where the current is returned. The base is used as the control terminal, where a small amount of current turns on and off the flow of current between the emitter and the collector.

When a voltage is applied to the base terminal of the PDTA143ZT,235, it allows for current to flow from the emitter to the collector. This enables amplification, selection, and switching, depending on the size of the current. In addition, the pre-biased collector voltage of the PDTA143ZT,235 allows for the regulation of output current from low to medium levels.
