TVS - Diodes Application Field and Working Principle

TVS diodes are an important part of the ESD Protection and Voltage Suppression Electronics Components. The TVS diode is also known as a Transient Voltage Suppression diode or Transil diode. The code MPLAD18KP78CAE3 represents a type of TVS diode with an 18KV transient surge rating and a peak pulse power of 78 watts.

TVS diodes are essential components in surge protection and voltage supression applications, and the MPLAD18KP78CAE3 diode is a reliable choice for these applications. The components are available in different sizes from 2mm to as large as 8mm, with varying ratings to meet different application requirements. The diode also comes in multiple leadforms, to suit different application requirements.

Working Principle

The MPLAD18KP78CAE3 TVS is designed to provide protection for full surge events, such as those encountered in lightning-prone locations. The diode has built-in silicon avalanche breakdown protection, which triggers when the voltage across the diode exceeds its breakdown voltage. It then quickly absorbs the current, reducing the voltage across the diode and protecting the circuits and components downstream.

The diode consists of two terminals, Cathode and Anode. The Cathode is the negative terminal and is connected to the main power source. The Anode is the positive terminal and is connected to the circuit or component that needs surge protection. The Anode will typically be connected to the ground, to ensure that the voltage is always within a safe limit.

The diode also comes with an integrated Thermal Shutdown Protection technology. This technology triggers if the power dissipation exceeds the pre-specified limit, and the diode reduces the voltage across the diode to protect circuits and components downstream. The thermal shutdown is then reset once the temperature has cooled.

Advantages

The MPLAD18KP78CAE3 is a reliable and effective voltage suppression and surge protection option. It will protect circuits and components from overvoltage events, spikes, and surges. The thermal shutdown technology is also useful for protecting against thermal overloads, ensuring that the diode and downstream components are kept safe.

The diode is also simple to install and requires minimal effort. It can be used in both AC and DC applications, making it a versatile and reliable protection option. The diode also features a wide variety of leadforms, allowing for easy integration into PCBs.
