TVS - Diodes

MXLPLAD18KP75CA Application Field and Working Principle

TVS – Transient Voltage Suppressors, more commonly known as TVS diodes, are used in electronics to protect circuits from unexpected voltage spikes which may arise as a result of electrostatic discharges, surges, and other types of ESD (electrostatic discharge) events. These devices are also known as Surge protection devices or electronic clamps. They are primarily used to protect sensitive components, circuits, and power supplies from over-voltage damage.

Based on their voltage requirements and reverse leakage current requirements, TVS can be broadly divided into two major categories – Unidirectional and Bidirectional TVS Diodes. Unidirectional TVS Diodes are used to suppress high-energy surges in one direction while Bidirectional TVS Diodes are used to suppress surges that occur on both sides of the line. The MXLPLAD18KP75CA is an example of a Bidirectional TVS diode.

The MXLPLAD18KP75CA is a Bidirectional TVS diode designed to protect high-speed digital circuits and user applications against ESD, Transient Voltage events, and power gaps. This device has low reverse capacitance and low clamping voltage while providing excellent performance at high frequencies. The MXLPLAD18KP75CA is suitable for applications such as automotive systems, industrial systems, multimedia systems, etc.

Working Principle of MXLPLAD18KP75CA

The working principle of the MXLPLAD18KP75CA involves two stages – Charge Discharge and Clamping. During the Charge Discharge stage, the diode reduces the voltage spikes that occur during ESD events to a safe level. This is accomplished by discharging a stored energy from a capacitor into the protected circuits. During the Clamping stage, the diode then clamps the output voltage of the protected circuitto a safe level until the event is over.

The MXLPLAD18KP75CA has a high breakdown voltage of 18KV and a low clamping voltage of 7.5V. This helps it to effectively reduce the noise level and protect circuits from current transients and voltage spikes. The high surge current rating ensures that the device can handle high power surges without getting damaged. Its low leakage current helps reduce power consumption and improve the efficiency of the protected circuit.

In addition, the MXLPLAD18KP75CA is also designed to provide excellent ESD performance, thermal stability, and dynamic RMS clamping. It features internal circuitry for temperature compensation, so that the clamping voltage and current remain constant even when operating under varying temperatures. The MXLPLAD18KP75CA also features a resettable fuse which helps protect circuits from sustained or long-term over-current/voltage events.

The MXLPLAD18KP75CA is available in a variety of packages, including SMA, SMB, DO-201AD, and SMC. This makes it easy to find the right package for a particular application. The device also features RoHS-compliant green material that helps make it more environmentally friendly.
