BZG05C20-HE3-TR3 is a single-rectifier diode designed for overload protection or over-voltage protection. It is widely used in power supplies, domestic appliances and automotive electronic systems. This article discusses the application field and working principle of BZG05C20-HE3-TR3.

Application Field

BZG05C20-HE3-TR3 has a wide range of applications. It can be used as a stabilizing element in power supplies and household appliances, such as electric motors, UPS systems, electrical circuits, and electrothermal controllers. In automotive electronics, BZG05C20-HE3-TR3 can protect against overvoltage in electric vehicle control systems, preventing the circuit from being damaged due to voltage spike.

Working Principle

BZG05C20-HE3-TR3 is a special type of diode, known as an avalanche breakdown diode. It is constructed with a p–n junction, with a heavily doped p-type layer and a lightly doped n-type layer. During normal operation, the diode behaves like a standard diode, and current flows from the anode to the cathode. When the voltage exceeds the breakdown voltage, the flow of current breaks down in the diode and the diode enters its breakdown region and begins to conduct current. This protection from over-voltage provides protection from damage and helps maintain the reliability of the circuit.

BZG05C20-HE3-TR3 is a very reliable and cost-effective solution for protecting consumer electronics from over-voltage. It is designed with a low forward voltage drop, high thermal robustness and high reverse-voltage capability. Its high reliability and low cost make it an ideal choice for a variety of industrial, consumer and automotive applications.
