MXSMLJ20AE3 Circuit Protection

The MXSMLJ20AE3 is a three-terminal, two-level over voltage protection thyristor from ON Semiconductor. It is mainly used in LCD TV, USB ports, and peripheral devices. The device is composed of two silicon junctions and one oxide PN junction plate.

Application Field
The MXSMLJ20AE3 is a transient voltage suppressing (TVS) diode used for protecting electronic components from damage due to voltage spikes. It is used in various applications including:

• Mobile phones
• Computers
• Televisions
• DVD players
• Video game systems
• Data storage devices
• Electronic circuits

The device is well-suited for use in automotive applications where over-voltage protection is needed. It is also suitable for use in industrial equipment, home appliances, and other high-end consumer electronics.

Working Principle
The MXSMLJ20AE3 has two thyristors and one protection diode. The device is designed to respond to voltage and current spikes as they are detected. When the spike surpasses the rated voltage, the device responds by turning off, creating an open circuit. This protects devices from damage caused by the repeated exposure to high voltages. The device\'s over-voltage protection is set to the factory default level. However, it can be adjusted to any suitable levels for a custom application. The device also features thermal shutdown capability, which prevents it from overheating when the voltage is higher than the rated value. When the temperature exceeds the rated value, the device immediately shuts down. The device is also designed to provide low capacitance and low leakage current. This allows it to provide maximum protection without compromising the speed of the signal.

The MXSMLJ20AE3 is a versatile and reliable protection device for various applications. It is designed to provide maximum protection while maintaining a high speed signal. The device is also resistant to shock, vibration, and temperature extremes, making it an ideal choice for various applications.
