MAPLAD18KP13A

TVS - Diodes

The MAPLAD18KP13A is a diode based device designed for Transient Voltage Suppression (TVS) applications. TVS diodes are semiconductor devices used for lightning and surge protection in circuits. They are designed to clamp voltage spikes on signals or power lines, which can damage sensitive electronic components and devices. TVS diodes are used in almost all consumer electronics, telecom/data, medical, power, automotive and military applications.

Application Fields

The MAPLAD18KP13A TVS diode is used primarily to protect against damaging voltage transients caused by nearby lightning strikes to ground or electromagnetic fields generated by switching off loads on power lines. TVS diodes are typically used for AC line protection, telecommunication line protection, and signal line protection. The MAPLAD18KP13A has been designed with a reverse peak pulse power of 18kW and a reverse peak voltage of 13V.

Working Principle

The working principle behind TVS diodes is based on their ability to ‘clamp’ transient voltages at a certain level. TVS diodes are designed to absorb and dissipate high energy transients. When a high voltage transient occurs, the diode switches to a forward conduction state, conducting the current and limiting the voltage. The current is then channeled to the diode’s anode and cathode connections, which are designed to dissipate the energy generated by the transient. After the transient, the diode switches back to its reverse conduction state, stopping the current flow. This process of switching is usually very fast, on the order of nanoseconds.

The MAPLAD18KP13A diode offers a reverse peak power rating of 18kW and reverse peak voltage of 13V, working together to protect sensitive circuits from damaging voltage transients. The diode’s surge capabilities make it suitable for use in a wide variety of applications such as automotive, military, telecommunications, and consumer electronics. The device also features a low dynamic resistance, allowing for more efficient power dissipation.
