TVS - Diodes - CDSOD323-T12L Application Field and Working Principle

TVS-diodes (Transient Voltage Suppressor-Diodes) are uni or bi-directional, overvoltage protection components designed to protect electronic equipment from destruction due to electrostatic discharge (ESD), inductive and electrical transients. The components used for this protection are generally known as TVS or TVS-diodes. The CDSOD323-T12L is a specific TVS-diode that is commonly used for protection in a wide range of applications.The CDSOD323-T12L is housed in a SOD323 package which measures 2.0mm x 1.25mm, providing a very compact size with minimum parasitics and associated power losses. The CDSOD323-T12L is capable of handling voltage transients up to 12V with stand-off capability of 7V. It has a maximum rating of 30A peak pulse current and 130W peak pulse power. This diode provides superior performance over many other TVS-diode solutions, making it suitable for a wide range of applications. The CDSOD323-T12L is typically used in high speed signal communication systems such as Ethernet, USB 2.0, HDMI, SDH/SONET, and Infiniband. It is also often used in consumer electronic products such as notebooks, PCs, servers, tablets, cameras, and gaming consoles. The low capacitance and high surge ratings of the CDSOD323-T12L make it suitable for applications requiring high speed ESD and EFT protections.The CDSOD323-T12L operates by clamping down voltage transients which exceed the breakdown voltage and limit them to the safe range. This diode is designed to operate at a very low voltage and is triggered by a very small amount of energy. Upon the detection of a voltage transient or ESD event, the diode immediately begins to conduct current once the breakdown voltage is exceeded, and current is diverted away from the circuit being protected. This diversion of current ensures that the current path is not the same as that of the normal operation, and protects the circuit from further damage.The CDSOD323-T12L also has a very fast response time, allowing it to provide protection on very short duration overvoltage/overcurrent pulses. The diode utilizes an ultra-fast reverse avalanche breakdown which allows it to recover quickly from overvoltage conditions. The combination of fast response time and low capacitance makes the CDSOD323-T12L ideal for high speed signal transmissions.In summary, the CDSOD323-T12L is a TVS-diode with many excellent features. Its small size allows it to fit into almost any application, and its fast response time allows it to provide protection on very short duration pulses. Its low capacitance and high surge ratings make it perfect for high speed signal communication systems, and its ability to protect against ESD and EFT events makes it a very versatile and reliable solution.
