TVS – Diodes is a form of semiconductor protection that are often used when higher protection and greater surge current handling capability are needed. They are often used to protect high technology systems such as computers, Ethernet switches, HDTV’s, mobile phones, and other sensitive equipment, as well as over-voltage, over-current and ESD protection needs. One of these TVS – Diodes is the CDSOD323-T24S diode.

The CDSOD323-T24S diode is a small, surface-mount, symmetrical, low capacitance, low-voltage transient voltage suppressor. It provides both ESD protection for delicate circuits as well as surge protection, and is capable of handling spike currents up to 100A. Its symmetrical design with two low voltage Zener diodes, and the integrated ESD protection on its cathode and anode (PAD) enable it to protect sensitive circuits from up to 16kV ESD pulses. This diode is also very low capacitance parasitic load when used in applications that have high-frequency signal lines.

The CDSOD323-T24S diode is designed for devices such as computer controllers, VoIP phones, security systems, gaming consoles, HDTV’s, hard disc drives, GPS receivers, etc. It can be used in both consumer and industrial applications where its ability to suppress a wide range of potential malfunctions or false operations could be used for a variety of protection purposes.

The CDSOD323-T24S diode works by providing a clamping circuit. This circuit must have a low voltage drop, which can provide the device with the protection it needs. This is accomplished by using a symmetrically-paired Zener diodes to lower the voltage, and the ESD protection on the cathode and anode (PAD) to guard against transient surges in the over-voltage range. The capacitor also branches off from this low-voltage line and acts as a dampener, providing further protection against high voltage (<35V).  The PAD also provides an additional level of protection to the device against any off-state leakage.

When a transient voltage surge happens, the Zener diode and ESD protection will activate and subsequent current conduction from the cathode and anode (PAD) will occur in order to limit the voltage waveform on the output line and protect the device from getting damaged. It is this combination of voltage limits, EMI protection, and transient voltage surge suppression (TVSS) that makes the CDSOD323-T24S diode such an effective and reliable component for providing reliable protection.

Overall, the CDSOD323-T24S diode provides an excellent combination of low capacitance, low-voltage, and transient voltage protection for a variety of applications. Its symmetrical, low capacitance, low-voltage design, combined with integrated ESD protection on its anode and cathode (PAD) provide reliable protection from both ESD pulses up to 16kV as well as current overloading. It is a great choice for protecting high-end electronics and consumer devices that require an advanced level of protection.
