MXLSMLG15CAE3 Application field and Working Principles

TVS-Diodes are an important part of electronic protection systems, used to protect sensitive circuits from electrostatic discharge and transient surges. MXLSMLG15CAE3 is an ultra low-capacitance, 12V, 15000W, bidirectional TVS-Diode product from ON Semiconductor that provides two-line surge protection in a compact SOT-23W package. This family of diodes is particularly suitable for a broad range of applications requiring good ESD, surge protection and low-capacitance performance.

Key Features and Benefits

• Ulta low capacitance of < 0.2pF offers optimal protection performance
• Low leakage current of < 10nA for improved ESD performance
• Unidirectional and bidirectional safety diodes
• Offers ESD protection up to 16 Kodi Wes
• SOT-23W package with PowerPAK® SC 3 (BiCD 0.13) technology

Applications

MXLSMLG15CAE3 is specially designed for applications that require both ESD and surge protection. They are particularly suitable in applications such as portable electronics, data and signal lines, Telecom line protection, and automotive infotainment.

Working Principles

The working principle of the MXLSMLG15CAE3 is simple. The diode is designed to provide two-line protection from electrostatic discharge and surge currents. When a voltage surge is present, the diode will switch, allowing the current to pass through the device without causing any damage to the sensitive components. This is done by the breakdown voltage of the diode, which is typically rated several hundred volts. When the voltage drops below a certain level, the diode will switch back to its off state, effectively blocking further current from passing through.

In addition to providing two-line protection, the bi-directionality of the diode means that it can protect against positive and negative voltage transients with equal effectiveness. This makes the MXLSMLG15CAE3 an excellent choice for bidirectional applications, providing twice the protection of a unidirectional diode.

Conclusion

The ON Semiconductor MXLSMLG15CAE3 is an ideal solution for providing two-line protection for high speed signal and circuit applications. Its ultra low capacitance of 0.2pF offers optimal protection performance, while its bi-directionality provides protection against both positive and negative voltage transients. With its SOT-23W package and PowerPAK® SC 3 (BiCD 0.13) technology, this diode is an excellent choice for a wide variety of applications.
