TVS - Diodes

A TVS - Diode is an electronic component used to protect electronic circuits from over-voltage transients, including lightning and electrostatic discharge (ESD). It is essentially a diode with a zener voltage exceeding the supply voltage. Common applications for TVS diodes include surge protection, over-voltage protection, and lightning protection.

MXPLAD18KP10CA Application Field and Working Principle

The MXPLAD18KP10CA is a Transient Voltage Suppressor (TVS). It is designed for transient overvoltage protection in high power applications. It is suitable for protecting low voltage power supplies against voltage surges, lightning, and ESD pulses. The MXPLAD18KP10CA is constructed of a glass-passivated junction, which significantly increases the surge handling capability and reliability.

In normal conditions, the TVS diode behaves like a common diode, releasing electricity in only one direction. It has a low forward voltage drop, and the current passing through the diode is limited only by the external source impedance connected in series. When the voltage exceeds the peak reverse voltage written on the diode, the silicon junction activates and the voltage is clamped to the zener voltage, thus protecting circuitry connected after the diode.

The MXPLAD18KP10CA has a peak reverse voltage of 18KV, a peak pulse current rating of 10A and a maximum peak power dissipation of 180W. The device is packaged in an hermetically sealed metal case which prevents any exposure to environmental contaminants and moisture. The package also ensures an isolation between positive and negative polarities so that the TVS diode can be used in polarities.

The MXPLAD18KP10CA is widely used in board-level protection devices, AC/DC power supplies, and other equipment exposed to ESD, surge, lightning, and other transients. As a low-capacitance device, it is suitable for high frequency lines, and for applications with high power dissipation requirements.

Conclusion

The MXPLAD18KP10CA is an excellent choice for circuit protection from transient over-voltage events. It is a fast-acting TVS Diode with high peak power dissipation, packaged in an hermetic case for protection against external contaminants. The device is suitable for a wide range of application, including board-level protection, AC/DC power supplies, and other equipment that needs protection from surge, lightning, and ESD.
