SMBJ220CATR

TVS - Diodes, otherwise known as transient voltage suppressors, are semiconductor devices used for overvoltage protection and isolation. They are designed to protect circuit components from high-voltage transient events such as lightning strikes, static electricity, and electromagnetic interference. SMBJ220CATR is a TVS diode which is suited for general-purpose, bidirectional transient suppression.

The SMBJ220CATR is a high-performance device that can dissipate 20 Watts of power for 8/20 μs surge events. It has an extremely fast response time which can be used to protect delicate or sensitive devices that require precise timing. The device has a 12V stand-off voltage and a 22V maximum clamping voltage. It is easy to use, as it requires no external components or heatsink to be installed.

The SMBJ220CATR is suitable for a range of applications, such as telecom and networking, automotive, and general purpose overvoltage protection. It can be used in high-speed circuits such as USB, Ethernet, and coaxial cables to provide isolation, provide edge protection, or as a general-purpose line protection. It can also be used to protect sensitive electronics from electrostatic discharge (ESD).

The SMBJ220CATR\'s working principle is based on the Avalanche breakdown effect, which is a process by which a large current is generated when the applied voltage exceeds a certain threshold. The device has a breakdown voltage of 12V and a maximum clamp voltage of 22V. When an overvoltage transient event occurs, the device begins to conduct, drawing current from the circuit and dissipating the current as heat. This limits the voltage across the circuit, thus protecting the components from damage.

The SMBJ220CATR is a reliable and cost-effective solution for high-speed circuit protection. Its fast response time and wide application range make it suitable for a variety of applications, including telecom and networking, automotive, and general overvoltage protection. Its ability to dissipate 20 Watts of power for 8/20 μs surge events make it ideal for protecting vulnerable components from high-voltage transient events.
