3KP78A

In this article, we will discuss the application field and working principle of 3KP78A TVS diode. TVS (Transient Voltage Suppressor) diodes are semiconductor devices that are designed to protect electronic circuits from transients, or sudden voltage surges, that can occur in the circuit and cause serious and even irreparable damage.

3KP78A TVS diodes are bi-directional devices that can be used in applications such as automotive, industrial, consumer, computing, and telecommunications applications. They provide voltage clamping, over-voltage protection, and ESD (Electrostatic Discharge) protection. The 3KP78A TVS diode provides a breakdown voltage of 78V, and has a reverse stand-off voltage of 54-75V, a forward voltage of 1.3V max, and a peak pulse power of 4800W.

The working principle of 3KP78A TVS diodes is based on the principle of electron flow. TVS diodes contain two layers of semiconductor material, an intrinsic layer and an extrinsic layer. When a voltage surge occurs, an excess of electrons from the extrinsic layer flow into the intrinsic layer, creating a current path that dissipates the applied energy, thus protecting the device.

TVS diodes are very efficient at providing protection and require minimal circuit design. They are ideal for high-speed data lines or sensitive, low-power circuits that require low stray capacitance. They can also be used in large circuits with high current capabilities.

The 3KP78A TVS diode is capable of protecting sensitive electronic components from electrical transients and surges. It is a reliable and effective device that is easy to install and use. It is a reliable and effective solution for providing over-voltage and ESD protection in the electronic circuits.
