TVS (Transient Voltage Suppressor) diodes are a type of semiconductor that helps protect a system from high voltage spikes and surges. These spikes can be created due to a number of different causes, including lightning, power outages, static electricity, and more. The 3KP190C is a type of TVS diode designed to be used as an overvoltage protection device in industrial control equipment.

The 3KP190C is available in a variety of packages and can be used to protect power circuit or equipment from overvoltage or surge currents. It is designed to handle up to 3000 watts per line of peak pulse power and is capable of handling up to 1kA of peak pulse current. The device is rated to provide up to 1800 volts of protection across a single line and is rated to protect up to 15kV of isolation. In addition, it is designed to be RoHS (Restriction of Hazardous Substances) compliant and has a high level of immunity to lightning and surge transients.

The main application field for the 3KP190C is in industrial applications such as motor controls, automation systems, power supplies, and other circuitry. The device can be used to protect the circuit from overvoltage, surge, or transient voltage. In addition, it can be used to protect power supplies and systems from lightning or ESD (electrostatic discharge) related events. The device is capable of providing protection up to 4kV without the need for external components.

The 3KP190C features unidirectional (avalanche) protection in the breakdown region, which helps to prevent arcing and premature failure. It also has a low clamping voltage (<1V) that helps to reduce losses across the diode. In addition, it has a low on-state voltage drop that helps to improve system efficiency.

The working principle of the 3KP190C is to provide protection against spikes or surges in the voltage by providing a low resistance path when activated. This low resistance path allows excess current to be diverted away from the system components, effectively protecting them from overvoltage or transient events. The device has a breakdown voltage of around 250V, and will start to conduct when the applied voltage exceeds this level. When the current drops below a certain level the device will stop conducting and the voltage will return to normal.

The 3KP190C is designed to provide a high level of protection against transient events in industrial applications. It is capable of handling up to 3000 watts of pulse power and can provide protection up to 15kV. In addition, it has a low clamping voltage and features an avalanche design which helps to reduce losses and improve system efficiency.
