Working principle

The BZX84C20TA works by using two diodes connected in series, a Zener diode and a regular diode. The Zener diode is reverse biased, meaning it is connected with its anode to the positive terminal of the power supply. In this state, it will only allow current to flow in one direction, from its anode to its cathode. The second diode is a conventional diode, also connected with its anode to the positive terminal of the power supply. This diode works as a shunt, allowing current to flow around the Zener diode. When the voltage across the Zener diode exceeds its breakdown voltage (Vz), the current will start to flow through it. This in turn lowers the voltage across the Zener diode, and the current will flow back and forth through the diodes to maintain a constant voltage.

Conclusion

The BZX84C20TA is a single Zener type diode, with a power dissipation of up to 0.5W. It is widely used for a variety of applications, from consumer appliances, industrial equipment, automotive and aerospace applications. Its features include a surface mount device and high surge capacity, making it suitable for voltage clamping and transient suppression applications. Its basic operation is based on two diodes connected in series, the Zener diode and the regular diode. The Zener diode is reverse biased, and when its breakdown voltage is exceeded it allows current to flow, which in turn lowers the voltage across the diode, maintaining the voltage at the desired level.
