Working principle of the ZTX694B

The ZTX694B is a type of BJT, which stands for bipolar junction transistor. It is a current-controlled device, as its output current is regulated by the input current. A BJT consists of three terminal devices (base, emitter, and collector), with the base being the controlling terminal. An input voltage applied to the base will control the flow of current from the emitter to the collector. The current from the collector is controlled by the input voltage applied to the base. So, in summary, the ZTX694B operates by controlling the flow of current from the emitter to the collector, based on the input voltage at the base.

Conclusion

In conclusion, the ZTX694B is a type of BJT belonging to the family of single transistors. It features 800mA maximum collector current, 625mW maximum power dissipation, 0.35V collector-emitter saturation voltage, and 80V breakdown voltage. It has a wide range of applications, from audio amplifiers, to oscillators, to light dimmers. Lastly, it operates by controlling the flow of current from the emitter to the collector, based on the input voltage at the base.
