SMBJ22A-Q

The SMBJ22A-Q is a transient voltage suppressor (TVS) diode designed for use in overvoltage protection and circuit noise mitigation applications. The SMBJ22A-Q is a bidirectional Unidirectional ESD Suppression Diode that relieves overvoltage stresses from transient spikes due to electrostatic discharge, inductive switching, cable slapping, and much more. It has a wide operating temperature range of -55°C to +175°C, making it ideal for a variety of industrial and commercial applications. Additionally, the SMBJ22A-Q is RoHS compliant, making it a great choice for environmentally conscious projects.

The SMBJ22A-Q is a 22-volt TVS diode commonly used in telecommunications and computer equipment. It is designed to provide overvoltage protection in applications where electrical noise and transient spikes due to electrostatic discharge (ESD) or from inductive switching can potentially cause permanent damage to sensitive elements. The SMBJ22A-Q has a low dynamic capacitance and is rated for an operating temperature range from -55°C to +175°C, making it a great choice for many industrial and commercial applications.

The working principle behind the SMBJ22A-Q is the development of a reverse breakdown voltage between the anode and the cathode. The TVS diode operates by creating a blocking voltage above which an avalanche breakdown takes place, providing an electrically-nonconductive path. Thismakes the device for desirable for ESD and other transient spike protection applications, since it can absorb high voltage transients while preventing any further voltage rise.

The SMBJ22A-Q is a bidirectional device, meaning that it can protect against both positive and negative transients. It blocks any voltage drop that exceeds its specified breakdown voltage, providing effective ESD protection and reducing the risk of damage to sensitive components. Additionally, the SMBJ22A-Q has a low leakage current and a low dynamic capacitance for better EMC performance.

The SMBJ22A-Q is an ideal solution for a wide range of applications including telecommunications, computer equipment, automotive electronics, and consumer electronics. It can be used to protect against ESD, inductive switching, cable slapping, and other transient spikes in any environment. The device is also suitable for applications where it may be subjected to extreme temperatures or corrosion, making it a great choice for harsh environments.

In summary, the SMBJ22A-Q is a bidirectional TVS diode designed for use in overvoltage protection and circuit noise mitigation applications. It has a wide operating temperature range, low leakage current, and low dynamic capacitance, making it ideal for many industrial and commercial applications. The device works by developing a blocking voltage above which an avalanche breakdown takes place, providing an electrically-nonconductive path and protecting against ESD and other transient spikes. As such, the SMBJ22A-Q is an ideal choice for a variety of applications where high transients protection is required.
