TVS diodes, or Transient Voltage Suppression diodes, are widely used in a variety of applications, from consumer electronics to industrial settings. One common type of TVS diode is the P4KE120HE3/73. This type of diode is one of the most popular models in the market and is used for protection against large voltage spikes and lightning. This article will explain the application field and working principle of the P4KE120HE3/73 TVS diode.

The P4KE120HE3/73 is a bi-directional TVS diode that is designed to protect against overvoltage. It is commonly used in order to prevent electronic components from being damaged due to surges in electrical current. It can also be used in conjunction with other protection devices, allowing for increased protection against overvoltage.

The P4KE120HE3/73 TVS diodes are typically used in a wide variety of applications. They are often found in automotive systems, such as powertrain, engine control, and airbag control units. As well, they are also used for protection in industrial control systems, home audio equipment, home entertainment systems, and other high voltage applications.

The P4KE120HE3/73 is a high performance, bu reliable diode that offers excellent reverse voltage and transient overvoltage protection. The diode is designed with a high-performance silicon structure that can reduce joule heating, extend the operational life and provide higher energy dissipation. Since the diode has a very low capacitance, it can be used in high frequency applications without compromising its performance. Additionally, the P4KE120HE3/73 has a very low leakage current, making it suitable for high temperature applications.

The TVS diode works by using a zener breakdown voltage to stabilize the current against large voltages. When the voltage across the TVS diode increases above the breakdown voltage, the diode begins to conduct, allowing the current to pass through. This current then flows in the opposite direction, providing protection against the large voltage spikes. As the voltage across the diode decreases, the diode stops conducting, allowing the current to drop back to normal levels.

The P4KE120HE3/73 is an excellent choice for high voltage applications due to its high energy dissipation capabilities and its low leakage current. This makes it suitable for use in a variety of applications, from automotive systems to industrial control systems. With its reliable performance and high-performance silicon structure, the P4KE120HE3/73 is a choice for those looking for high quality protection against large voltage spikes.
