BCX70J,235

Transistors - Bipolar (BJT) - Single

The BCX70J,235 is a type of transistor known as “single” bipolar (BJT). It is a relatively small, reliable and easy-to-use transistor that is used for a wide variety of applications. The BCX70J,235 has a maximum power rating of 100 mW, a maximum collector current of 10 A , a maximum collector-emitter voltage of 70 V, and a typical frequency range of 1 MHz – 1.5 GHz.

Applications

The BCX70J,235 is primarily used in RF switching and mixing applications where the high frequency performance is valuable. It is also suitable for low power amplifiers and in circuits that require a low noise level and low distortion. It is also widely used in applications such as oscillators, mixers, attenuators, detectors, and amplifiers and systems containing transistors.

Working Principle

The BCX70J,235 functions using the same principles of operation as other transistors, with the main difference being its low noise and low distortion. A BCX70J,235 transistor is a three-terminal device with an emitter, a collector, and a base. The base is the control terminal, and the collector and emitter are the output terminals. When current flows from the base to the emitter, it causes a small current, called a base current, to flow from the base to the collector. This base current then controls the collector-emitter current. When a voltage is applied to the base, the collector-emitter current increases, thus amplifying the input signal.

At the collector terminal, the transistor increases the power of the coupled signal, transferring it to the next stage or the output. At the same time, the transistor can be used to block the reverse current flow. For instance, when the base voltage is zero, no current will flow from the collector to the emitter, thus blocking the reverse current flow.

Conclusion

The BCX70J,235 is a single-bipolar (BJT) transistor that offers excellent radiofrequency (RF) performance, low noise and low distortion. It is a reliable and easy-to-use transistor that is suitable for RF switching and mixing applications, amplifiers, and other circuits. With its low power consumption, high collector current, and low voltage, the BCX70J,235 is a great choice for applications where high performance and reliability is required.
