FJNS4209RTA are transistors categorized in the group of bipolar junction transistors (BJT) for single, pre-biased applications. These transistors are manufactured by Fairchild Semiconductor and are one of the most popularly used types of transistors. The FJNS4209RTA transistors are designed to be used in systems that require low- and high-frequency switching and amplifying applications.

The FJNS4209RTA transistors are built on the NPN transistor architecture and can handle a continuous collector current up to 1.5 Amp. The maximum voltage that these transistors can handle is about 300 Volts. The input capacitance for these transistors is about 140pF and the turn-on time for these transistors is around 25nS.

The working principle of FJNS4209RTA transistors is simple. When current is supplied to the base terminal of the FJNS4209RTA transistor, an amplified current is produced at the collector terminal. This current at the collector, called the amplified current, can be used to control external devices, such as motors, lights, etc. The amplified current’s strength is proportional to the current supplied at the base terminal.
