In home automation applications, it can be used for motor and motor speed control, as well as for light dimming and detection. Finally, it is also suited for light load switching applications such as monostability, temperature control and miniaturized electronic circuits.

Working Principle

The BCX799_J35Z is an NPN transistor that works on a simple principle. It is composed of two junctions –a base-emitter junction and a base-collector junction. When the base-emitter junction is forward biased, a voltage difference will develop between the base and emitter and current will flow through the emitter-collector path. This current, combined with the voltage in the base-collector junction and with the triggering bias current, will determine the amplitude of the collector current. As the collector current increases, the voltage in the base-collector junction will also increase, and the transistor will become more fully saturated. Furthermore, the transistor will remain saturated until the voltage in the base-collector junction is decreased.

Conclusion

The BCX799_J35Z is a versatile single bipolar Junction Transistor designed for low voltage and high power control applications. It is ideal for use in automotive, industrial, and home automation applications. Its power rating of 30W, drain-source voltage rating of 30V, and low side switching capacity of 50mA make it an excellent choice for various applications. Its working principle is based on the simple idea of using two junctions –a base-emitter junction and a base-collector junction- to determine the collector current and achieve saturation. Overall, the BCX799_J35Z is an efficient and reliable transistor that is suitable for a broad range of applications.
