TVS (Transient Voltage Suppression) diodes are used to protect sensitive electronic components against high transient voltages. The CD214C-T45CALF is a modified low capacitance silicon avalanche diode. It has high surge capability and low capacitance. It is suitable for data line protection in high-speed data systems applications.

The CD214C-T45CALF is a unidirectional device that works by diverting high transient voltage away from delicate electronic components. It helps to reduce the peak voltages which might otherwise cause permanent damage to these components. The device consists of a body diode that is connected in series with an avalanche diode. To provide better protection against transients, the avalanche diode acts as a clamp and dissipates large amounts of energy.

This device has relatively low capacitance, which makes it ideal for protecting high-speed data lines. It has a low clamping voltage and can handle high peak power, making it suitable for signal line protection in telecommunication systems. The device is designed to withstand a high surge capability and has a wide breakover voltage range of 3V to 6V.

The CD214C-T45CALF TVS diode works in the following way. When a transient voltage impulse is applied to the circuit, the body diode begins to conduct. This quickly raises the current in the circuit and the avalanche diode goes into breakdown. This in turn causes the body diode to become forward biased and the clamped voltage across the device rises quickly to its peak value. The peak voltage is clamped by the avalanche diode and the total energy dissipated by the device is less than the energy stored in the body diode.

After the transient has been dissipated, both the body diode and the avalanche diode will be off and the device will be in its non-conducting state. The device is designed to be self-recovering and will be able to withstand multiple pulses without degradation.

The CD214C-T45CALF TVS Diode is suitable for data line protection in applications such as telecommunication equipment, computers, LAN networks, electronic instrumentation, and other systems which require transient overvoltage protection. It is also suitable for use in industry, automotive, and consumer electronics applications.

The CD214C-T45CALF is also ideal for protecting against power line utility switchgear transient overvoltages. It is capable of withstanding transients up to 40kA, making it suitable for heavy industrial and plant applications such as uninterruptible power supplies and generator monitors.

The CD214C-T45CALF TVS diode is a high-performance device which provides superior protection against transient voltage surges. It is suitable for a wide range of applications and is designed to withstand high peak power surges while providing low capacitance performance.
