TVS diodes, also known as Transient Voltage Suppressors (TVS) are basically overvoltage protection devices which have the purpose of protecting electronic circuits from damage due to excessive voltages or transients. The CD214L-T6.5CALF is a mini-size and ultra-low capacitance two-line transil TVS that helps protect high-speed data line applications. It is specifically designed for signal integrity, ESD, and EFT protection.

The CD214L-T6.5CALF Application Field and Working Principle

CD214L-T6.5CALF TVS are designed specifically for high-speed data line applications that require a low capacitance, such as USB 3.0, BroadR-Reach and MIPI M-PHY. It also gives exceptional ESD protection to a wide range of delicate and high-end electronic devices, such as digital cameras, high resolution monitors, iPads and more.

The CD214L-T6.5CALF is a two-line transient voltage suppressor (TVS) that provides up to 6.5kV of ESD protection. It is designed to reduce the effects of EMI/RFI on electronic components. It also provides low capacitance (<0.25pF) protection for data lines operating at 9.2Gbps or higher. The CD214L-T6.5CALF is capable of handling transients with a peak pulse power (TPP) of 600W at 8/20µs and is designed with an 8mm² footprint.

The working principle of the CD214L-T6.5CALF is based on how a Zener diode works. When the input voltage exceeds the Zener voltage, the diode turns on and creates a short circuit. The current flowing through this short circuit then creates an electrical pressure on the Zener diode which helps to regulate the circuit. The Zener voltage is an integral part of the TVS and is configured to limit the output voltage to a safe level. When the input voltage decreases, the diode turns off and the output voltage returns to its normal operating value.

The CD214L-T6.5CALF has a peak pulse power rating of 600W which means that it can handle a very large amount of current. This is important when using the device to protect high-speed data lines, as it ensures that the data being transferred is not corrupted or lost. The device also features a very low capacitance of 0.25pF, which helps to reduce signal degradation and ensure that signals can travel at very high speeds without distortion.

In addition to providing excellent ESD and EFT protection, the CD214L-T6.5CALF is also capable of handling transients with a peak pulse power (TPP) of 600W at 8/20µs. This device is a great choice for a wide range of applications, from consumer electronics to industrial equipment, and offers reliable protection for sensitive components.

In summary, the CD214L-T6.5CALF is a great choice for high-speed data line applications that require a low capacitance and excellent ESD, EFT and transient protection. The device works by utilizing a Zener diode which turns on when the input voltage exceeds the Zener voltage. The Zener voltage is configured to limit the output voltage to a safe level. The device also has a peak pulse power rating of 600W, making it ideal for protecting high-speed data lines, and a very low capacitance of 0.25pF, which helps to reduce signal degradation.
