Transient Voltage Suppression (TVS) diodes are the most common devices used to protect sensitive electronic components from over-voltage transient impulses. TVS diodes have been around since the 1960s and are a key component of many electronics applications today.

The 3KP22 is a type of TVS Diode, which provides a very high nonlinear capacitance to protect against hazardous electrical transients. It is designed to rapidly clamp the voltage when high voltage transients occur, protecting sensitive electronic components from being damaged.

The 3KP22 is a lateral triple junction diode with an operating voltage of 7000V which is designed for interrupting and filtering of transients in a wide range of applications. There are two main types of 3KP22 devices – one type is designed for use in non- pulsed applications such as snubber and filter circuits, and the other is a surge type designed for use in high pulse current / frequency applications.

The 3KP22 device works by having the three junctions connected in series, with each junction being connected to a different voltage level. When a transient event occurs, the 3KP22 rapidly clamps the voltage, allowing for the protection of the electronic component from the transient. The rapid clamping action is achieved through the combination of the non-linear characteristics of the three junctions and the capacitance of the diode itself.

The 3KP22 can be used in a wide range of applications, where it is important to protect sensitive electronic components from over-voltage transients. This includes automotive, aerospace, telecoms and consumer electronics. In the automotive field, the 3KP22 is used to protect vehicles from the electrical transients caused by the spark of the ignition, and in aerospace applications it is used to protect aircraft from the electrical transients caused by lightening strikes. The 3KP22 is also used in telecoms applications for voltage protection, and in consumer electronics such as TVs and computers for surge protection.

The 3KP22 is a very effective device for protecting sensitive electronic components from over-voltage transients. It offers a very high nonlinear capacitance which helps to rapidly clamp the voltage, preventing any damage being caused to the component. The 3KP22 is used in a wide variety of applications, and is a key component in many electronics designs today.
