TVS Diodes are often used in the protection of electronic components such as transistors, resistors and diodes from excessive transient voltages. The MXSMLJ100A series of transient voltage suppressors is designed to provide protection from transient over voltages that may be applied to sensitive electronic components. The MXSMLJ100A series is composed of two distinct sub-circuits. The first one is an avalanche diode, which can handle voltages up to 1000 volts and is designed to clamp high transient voltages. The second one is a varistor, which is designed to offer protection from intermediate transient voltages that do not damage the components. This combination of two sub-circuits ensures that the device is able to protect against both high and low transient voltages.

The MXSMLJ100A is fully compliant with RoHS directives and meets the requirement of SHT (Safety, Health and Technical) directives for electronic device safety. The device has a ultra-low capacitance of 8 pf and a low dynamic resistance of 0.14 Ohms. Its rated reverse breakdown voltage is 100V, and its peak surge current is 7500A (10 x 1000μs). This device is also capable of dissipating a maximum power of 7.5 W.

The amazing properties of the MXSMLJ100A make it an ideal choice for various applications. Its low leakage current and ultra-low capacitance make it suitable for protection of sensitive I/O ports of computer systems, telecom equipment, Local Area Networks (LANs), etc. The device is also ideal for protection of automotive components such as switches, relays, ignition systems and audio systems. The device can also be used in medical equipment, instrumentation and even in digital media such as USB drives.

The working principle of the MXSMLJ100A is quite simple. Whenever a voltage exceeding its reverse breakdown voltage is applied to the device, the avalanche diode of the device begins to conduct, thereby limiting the voltage at its output. When a higher voltage is applied to the device, the varistor portion of the device conducts, which in turn limits the voltage at its output. This protects the sensitive components against excessive transient voltages.

The MXSMLJ100A is an excellent device for providing transient protection to various types of sensitive electronic components. Its low capacitance and high surge current rating make it suitable for a wide range of applications. It is also compliant with RoHS directives and offers excellent protection against both high and low transient voltages.
