A Transient Voltage Suppressor (TVS) diode is an electronic device designed to protect sensitive electronics from voltage transients, or spikes, that may last for a few nanoseconds up to several milliseconds. TVS diodes are ideal for protecting against lightning, power line transients, electrostatic discharges (ESD), and other unexpected voltage transients. The 3KP14A is a unidirectional (unipolar) diode with a clamped breakdown voltage of 14V, suitable for protecting sensitive electronic equipment from transient overvoltage conditions. It can be used in AC/DC and DC/DC applications and provides the user with an economical solution for suppressing transients.

The 3KP14A consists of three components: anode, cathode, and a ceramic core. It is a planar device with two electrodes, the anode and the cathode, embedded in a ceramic matrix. The ceramic core formed by the anode and the cathode is the actual device, which acts as a resistor to limit transient voltages.

When a transient voltage is applied to the diode, the anode and the cathode become conductive. Once the transient voltage reaches a certain threshold, the diode will quickly switch from an open circuit to a closed circuit, allowing current to flow through the ceramic core and suppressing the transient voltage.

The 3KP14A is typically used in applications that require protection from ESD, power line transients, and lightning. Due to its low profile design and small footprint, it is ideal for use in limited space applications. It is also often used as a secondary protection against failure of the primary protection device, such as a fuse or an MOV.

The 3KP14A is a great choice for many applications that require reliable transient voltage protection. It is relatively inexpensive, has a low on-state resistance, and can withstand high current surges. Furthermore, the ceramic assembly provides a high thermal conductivity and tight clamping characteristics, making it an ideal choice for a variety of applications.
