TVS - Diodes are transient voltage spikes protection devices used in various electronic applications. TVS-Diodes help reduce the voltage that reaches a vulnerable component. The CD214B-T160ALF is a TVS-Diode from Vishay’s Transil line. This product comprises a silicon diode and a power MOSFET in an SO-8 package. It can handle high current surges and offers high electrostatic discharge protection. The short-circuit failure rate is very low thanks to its power MOSFET.

The CD214B-T160ALF has two main application fields:

• Gas discharge tube (GDT) applications
• Surge protection applications

The GDT applications of the CD214B-T160ALF involve protecting two-wire transceivers from ESD and overvoltage events in automotive applications. This product includes an integrated MOSFET, providing the best possible protection to the circuit. The drain pin provides an external connection capability. This feature allows the possibility of adding additional insulation and protection layers.

The surge protection applications involve working with high DC and AC overvoltages. The CD214B-T160ALF provides a fast and effective switching response, enabling it to limit inrush currents and voltage spikes. This makes it perfect for applications where a high degree of overvoltage protection is required. The product also enables a cascading of currents thanks to its MOSFET.

The working principle of the TVS-Diodes involve the application of an arc of electricity from a short-circuit. The arc passes between two terminals of the diode and is made of hot gases. The arc is extinguished by the MOSFET, producing a high-speed current and voltage peak.

The CD214B-T160ALF works according to the basic working principle of TVS-Diodes. The arc is created when the current between the two terminals reaches a certain maximum level. When this occurs, the MOSFET immediately turns off the circuit, allowing the voltage and current peaks to be limited and the sparks to be extinguished. This way, the TVS-Diode offers both a surge protection device and an arc extinguishing device.

The CD214B-T160ALF is an ideal product for applications where a high degree of overvoltage protection is needed. Its two main application fields are GDT applications and surge protection applications. The device works according to the working principle of TVS-Diodes. It limits the current and voltage peaks, allowing for the protection of vulnerable components from overvoltage and short-circuit events.
