Transient voltage suppressor (TVS) diodes are a type of protection device that is used for circuit protection. They can also be referred to as “protective diodes” or “clamping devices”. The 3KP130A is an example of a TVS diode designed to protect sensitive electronic circuits from damage due to up to 40V transient voltages.

The 3KP130A employs a zinc oxide varistor as its main body, with three elements formed or connected in series. The device consists of two leads (anode and cathode) and a body (n-type). When a voltage is applied across the leads, the diode conducts current in the forward direction, as the anode voltage and cathode voltage become equal. When a transient voltage is applied across the diode, the body voltage and the cathode voltage become unequal, and the current is blocked.

The 3KP130A is used in applications where electrical transients, such as electromagnetic interferences (EMI) and electrostatic discharges (ESD), must be suppressed in order to protect the application\'s delicate components. The device can protect an application from up to 40V of transient voltage, and is available in a variety of commonly used footprints for easy placement in the application.

This device is designed to clamp transients to the VBR value of the device. This means that the device will act as a constant voltage source that will maintain a constant desired voltage within the circuit, regardless of the transient voltage. The device also has a self-resetting capability, meaning that it is capable of resetting itself after an event without the need for external means of resetting.

The 3KP130A has a nominal breakdown voltage of 40V (VBR = 42V) and a maximum peak pulse current of 13A. Its reverse leakage is 100nA and it can handle up to 25A peak pulse current with an 8/20µs waveform. It is also RoHS compliant and UL listed.

In conclusion, the 3KP130A is a highly effective TVS diode that can protect sensitive electronic circuits from up to 40V of transient voltage. Its self-resetting capability, UL listing, and RoHS compliance make it an ideal choice for protecting application components from electrical transients.
