TVS - Diodes

TVS - Diodes take advantage of the Avalanche effect and provide extremely high surge levels of lightning and ESD protection without the need for additional components. They are frequently used in applications such as Portable Medical Equipment, Automotive, Avionics, and Industrial Power Control Systems.

CD214C-T18CALF Application Field and Working Principle

The CD214C-T18CALF from Littelfuse is a low-capacitance high-surge and Ultra-Low Leakage (ULL) TVS Diode. This device is designed for ESD, Lightning, and Power Transient protection of other electronic components. It has an operating voltage range of 24V and a low clamping voltage of 26V. The component delivers high surge levels with a peak pulse current rating of 1500A (8/20µs). It exhibits a low capacitance of 4.2pF typical and low leakage current of only 0.1mA.

The CD214C-T18CALF has an ultra-low capacitance compared to conventional Multi-Layer Varistors (MLV) of 14.7pF. And the required operating voltage is much lower at 24V compared to MLV\'s rated at 38V. The very low leakage current and low capacitance combine to provide faster response to transient voltage events. This results in reduced ESD and surge damage to other electronic components.

The working principle behind the CD214C-T18CALF is that when a voltage is applied to the diode, the Avalanche effect kicks in and the diode can withstand higher voltages than the conventional breakdown voltage. This results in a sharp clamping of the voltage, preventing the voltage spikes from damaging sensitive electronics.

The CD214C-T18CALF provides high levels of ESD, Lightning, and Power Transient protection for many applications, including portable medical equipment, automotive, avionics, and industrial power control systems.

The CD214C-T18CALF is a robust component with a low power dissipation and excellent ESD protection capability. This makes it suitable for use in a number of applications such as safety, ESD, thunderstorm lightning protection, and sensitive electronics protection in industrial, automotive, avionics, and medical applications.

In conclusion, the CD214C-T18CALF from Littelfuse is an Ultra-Low Leakage (ULL) TVS diode designed for ESD, Lightning, and Power Transient protection of other electronic components. It delivers high surge levels and features a low capacitance of 4.2pF typical and low leakage current of only 0.1mA.
