In this article, we will discuss the application field and working principle of the BZX585-C3V3,135.

Application Field of BZX585-C3V3,135

The BZX585-C3V3,135 is a versatile diode that can be used for a variety of purposes. It is commonly used for voltage regulation. In this application, the diode is connected to a power source and regulated to a specific voltage level. This allows the power supply to safely deliver the desired voltage level to the load, protecting it from any voltage surges. Additionally, this diode can also be used in voltage clamping applications. In this application, the diode is connected in parallel with the load and clamps the voltage to a certain value, protecting the load from any sudden overvoltage.

The BZX585-C3V3,135 can also be used for audio applications. It is used as an electrostatic discharge (ESD) protector, which helps to reduce the chances of loud, harsh noises or other disruptions in the audio. This can help to improve the listening experience of the user. Furthermore, this diode can also be used for switching applications. Its low forward voltage drop makes it a good choice for such applications, as it helps to improve efficiency and power consumption.

Working Principal of BZX585-C3V3,135

The BZX585-C3V3,135 is a unidirectional diode and operates according to the principle of forward bias, which is a type of diode operation wherein the diode allows current to flow through it when the voltage is higher on the anode than the cathode. In the forward biased condition, current passes through the diode from the anode to the cathode and causes the voltage across the diode to drop. This is known as the forward voltage drop.

However, when the diode is subjected to a voltage higher than its breakdown voltage, which in this case is 3V3, current starts flowing from the cathode to the anode, a process called Zener breakdown. This reverse current is limited by the resistance of the diode, which is quite low, resulting in a relatively high current. The reverse current is also very temperature dependent and decreases as the temperature rises. This phenomenon is called Zener breakdown voltage or Zener voltage, and is used in voltage regulation and voltage clamping applications.

Conclusion

In conclusion, the BZX585-C3V3,135 is a versatile single diode that can be used for a variety of purposes such as voltage regulation, voltage clamping, audio applications, and switching applications. Its breakdown voltage of 3V3 helps protect electronic components from overvoltages, while its low forward voltage drop aids in improving efficiency and power consumption. Finally, the diode operates according to the principle of forward bias, where current flows from the anode to the cathode, and also according to the principle of Zener breakdown, where current flows from the cathode to the anode if the voltage exceeds its breakdown voltage.
