Working Principle

The PbSS4350X,147 is an NPN type single bipolar junction transistor (BJT). It consists of three charged particles, including two Emitter (E) and one Collector (C). The Emitters are connected to one side of the base, and the Collector is connected to the other side. When an increasing current is applied, the electrons from the Collector are attracted towards the Base and the holes from the Emitter are repelled away from the Base. This creates an electric field between the two diodes and provides current amplification for the base circuit. Since the base is connected to the Emitter and Collector, when electrons move in the Base-Emitter region, holes also move in the Base-Collector region, in opposition to the applied current. This creates a potential barrier at the Base-Collector junction and further increases the current gain.

Conclusion

The PbSS4350X,147 is a single-mode transistor that offers high voltage, high current gain, and fast switching capability in a ceramic DO-4 package. It has a breakdown voltage of 600V and is capable of withstanding up to 1A of collector current. It has a high frequency response of up to 7MHz and a thermal stability that can withstand up to 200°C of temperature. It is suitable for use in audio amplifiers, motor control, and DC switching applications. Its fast switching leads provide accuracy and precision. This makes the PbSS4350X,147 a versatile device, capable of operating in a variety of applications.
