TVS – diodes are becoming increasingly important components that are used in electronic circuits to protect sensitive circuits from overvoltages. The MXSMLG45CAE3 is a general purpose transient voltage suppressor diode designed for applications in industrial, commercial and consumer electronics.

The MXSMLG45CAE3 provides protection against ESD, lightning and power surge induced transient voltage events, and is ideal for protecting high speed logic and signal lines. It is capable of absorbing repetitive ESD discharge up to 8kV, making it ideal for applications that require reliable protection from electrostatic discharge.

The MXSMLG45CAE3 consists of a pair of high-voltage diodes connected back-to-back. These diodes clamps the voltage to a safe level by allowing a controlled current flow during an overvoltage condition. The device is housed in a compact 4-pin SOD-882A surface mount package, making it suitable for applications where space saving is essential.

The working principle of MXSMLG45CAE3 is relatively simple. The device contains two diodes connected in a back to back configuration. During a transient overvoltage condition, the voltage across the device surges up, causing the diode to start conducting. As the voltage increases, the diode characteristics causes it to clamp the voltage to a safe level and the device absorbs the excess energy.

In order to ensure reliable protection against up to 8kV ESD pulses, the MXSMLG45CAE3 features a patented transient thermal-rejection feature. This feature causes the device to self-regulate by adjusting its thermal rejection performance to compensate for induced thermal stress during a transient pulse. This ensures consistent device response and performance during repetitive ESD pulses.

The MXSMLG45CAE3 can be used in a wide variety of applications, including automotive, consumer electronics, medical, wireless and networking devices. It is also suitable for use in applications that require surge protection, such as power-over-ethernet systems, solar power systems, and uninterruptible power supplies. In addition, the device can be used in applications that require reliable protection from lightning or power surge induced transient voltage events.

The MXSMLG45CAE3 is a versatile diode that combines protection, reliability and cost-effectiveness in a single package. With its features and flexibility, the device is suitable for a variety of applications where transient protection is required.
