TVS diodes are overvoltage protection devices which protect sensitive electronic circuits from high-voltage transients, also called "spikes" in surge or transient voltage protection. The 3KP190CA is such a device, with an application field and working principle.

3KP190CA, a bidirectional device, features an avalanche rated diode with a bidirectional Transil element. Its discrete nature allows it to provide a high degree of transient overvoltage protection with very low clamping voltage. It is well-suited for applications that require a low voltage, bidirectional ESD protection device. Examples can be portable and personal electronic equipment, such as mobile phones and personal computers.

The working principle of the 3KP190CA is based on the avalanche breakdown of heavily doped silicon done. When a transient overvoltage is applied, the built-in Transil element triggers an avalanche energy to clamp the overvoltage. In other words, the breakdown voltage clamping action of the 3KP190CA protects the electronic system from surges and transients on either end of the diode, thus providing a safe operating environment.

The 3KP190CA is designed to survive severe surge stress events with a minimum number of components and the lowest possible cost. Its small axial-leaded package makes it ideal for use in compact telecom applications. The diode is capable of handling up to 3kA peak pulse current (8/20µs) and can handle pulse power values up to 500W. The diode is also very reliable, with a surge lifetime capability of up to 40,000 surges.

In summary, the 3KP190CA is an ideal overvoltage protection device for a wide range of applications. It can provide effective protection to sensitive electronic systems from the damaging effects of high-voltage transients and surges, as well as high pulse power events. Its discrete nature also makes the 3KP190CA very reliable and cost-effective, making it a great choice for many different applications.
