MSMLG170A is a thyristor-controlled surge protective device (TSPD) for in-vehicle DC/DC converters and unregulated power supplies. The device is designed for industrial, automotive, medical, consumer and other electronic applications requiring robust ESD and EFT protection. The MSMLG170A works by controlling the current flow from the voltage source to the load using a thyristor. When an over-voltage event occurs, the thyristor is triggered, which shunts the excess current away from the protected line. The MSMLG170A also utilizes a metal oxide varistor (MOV) to help protect against high-speed transient over-voltage events such as lightning strikes and electrostatic discharge. The MOV is designed to swiftly absorb the transient by diverting excess energy away from the protected circuit.

The MSMLG170A is designed for applications in which a low capacitive-type solution is desirable. The device is available in three different package sizes and offers robust surge protection up to 12V. The MSMLG170A can be used in automotive, data communications, industrial, medical, consumer, and other applications requiring robust ESD and EFT protection. The device is fully compliant with automotive EMI regulations, such as ISO 7637-2, and has also been tested in accordance with UL1449 4th Edition standards.

In addition to its robust protection capabilities, the MSMLG170A has low clamping voltage and low capacitance. The device also features excellent voltage and current handling, as well as high temperature durability. The low capacitance of the MSMLG170A ensures that its performance remains consistent over a wide temperature range, even in harsh industrial environments. In addition, the device is RoHS compliant, which means it is free of hazardous substances.

In terms of working principle, the MSMLG170A utilizes an auto-triggered thyristor to control the current flow from the voltage source to the load. When an over-voltage event occurs, the thyristor is triggered, shunting the excess current away from the protected line. The device also utilizes a metal oxide varistor (MOV) to help protect against high-speed transient over-voltage events such as lightning strikes and electrostatic discharge. The MOV is designed to swiftly absorb the transient by diverting excess energy away from the protected circuit.

Finally, the MSMLG170A is made with a low capacitive-type design, which makes it ideal for automotive, data communications, industrial, medical, consumer, and other applications requiring robust ESD and EFT protection. The device features excellent voltage and current handling, as well as high temperature durability, making it suitable for a variety of applications. The MSMLG170A is a reliable and durable device that can be used to protect your sensitive electronic equipment from over-voltage events.
