FCX558TA is a single bipolar junction transistor (BJT) designed for use in mobile equipment applications such as CDMA, GSM, EDGE, and WiMAX. It is also an ideal choice for low power and noise-sensitive applications, such as automotive, consumer electronics and medical equipment. The FCX558TA is a low voltage, low current device with a high input impedance and a low output impedance. It has a maximum operating voltage of 4V and a maximum current rating of 50mA. The device is also capable of withstanding a reverse voltage of 8V.

The FCX558TA is a NPN silicon epitaxial transistor (NPN-Cisco) that is specifically designed to provide high-speed switching in both low and high current applications. It has a wide operating range of 0.05 to 200mA. The high-efficiency switching of this device makes it an ideal choice for applications where fast turn-on and turn-off are required. It is also highly tolerant to thermal effects and ESD. It has a collector-emitter breakdown voltage (BVceo) of 30V, an emitter-base breakdown voltage (BVebo) of 6V, and an open-emitter voltage (Veeo) of -0.7V.

The FCX558TA features a low voltage on-resistance of 0.6Ω at -4V. Its low capacitance and low power make it an efficient device for low power and noise-sensitive applications. It is suitable for use as a switch or inverter in various applications.

The working principle of the FCX558TA is based on the transistor action. The device consists of three terminals: the collector, base, and emitter. The base terminal is used to control the flow of current between the collector and the emitter. When a voltage is applied to the base, the collector current increases. This increase in current causes the collector voltage to decrease, resulting in a current flow between the collector and the emitter. By regulating the base voltage, the current flow between the collector and the emitter can be controlled.

The FCX558TA is widely used in a variety of different applications, including automotive, consumer electronics, and medical equipment. It is suitable for use in radio frequency (RF) amplifiers, switch mode power supplies (SMPS), switching circuits, and digital logic circuits. It is also suitable for use as a low side switch in a high side current switching circuit.

The FCX558TA is a convenient, high-performance solution for a variety of applications. It has a low voltage on-resistance, low power consumption, and high input impedance and low output impedance. Its wide operating range and capability to withstand thermal effects and ESD make it an ideal choice for low power and noise-sensitive applications. The transistor action also makes it ideal for use as a switch or inverter in various applications.
