TVS-diodes are important components of electronic circuits, and of all the possibilities available, one of the most popular is the MSMCJLCE60A. Its application field and working principle will be explained in the following article.

The MSMCJLCE60A is an integrated circuit in a Small-Phillips Ultra Low-Capacitance package specifically designed for protection of USB, HDMI, and other I/O interfaces. It is a bi-directional TVS diode with low capacitance and low reverse leakage current designed to protect sensitive circuits from damaging electrical interference. The component is also suitable for suppressing the transient voltage spikes that can occur in noisy high-energy capacitive circuits. The low capacitance means that it won’t prevent high-speed data transmission at the normal rate.

The MSMCJLCE60A is rated at 60 volts and can handle repetitive surges of up to IEC61000-4-5 (Level 3) 24A (8x20µs), making it ideal for use on data lines that carry power as well as signals. It has a maximum capacitance of 8pF at 6.5V, 1MHz.

The key principles of operation bound with the MSMCJLCE60A are fundamental to any TVS diode, as they involve the structure and composition of the component. It consists of two opposite-facing diodes, each with their own body diode junction. A TVS diode will remain in its “off” state until a certain voltage is reached, at which point the two junction diodes become forward biased and conduct current. The voltage at which this occurs is called the diode’s “breakover voltage”. Once the diode is in forward-biased mode, it will continue to conduct until the voltage goes below a certain level, at which point the device will return to its “off” state. This is the reverse breakdown voltage.

The MSMCJLCE60A can be used on a range of devices where electrical interference or voltage spikes are a risk, such as high-power drives, computers, audio/visual systems, USB data lines, and other similar consumer electronics. It has a low capacitance for high-speed data transmission, a fast response time, and a low reverse leakage current to help protect sensitive circuitry. It can be used on high-speed data lines, where it will protect against voltage spikes of up to 60V.

In conclusion, the MSMCJLCE60A is an integrated circuit designed specifically for protection of audio/visual equipment and other electronics from the effects of voltage spikes or electrical interference. It consists of two opposite-facing diodes connected in series, and has a low capacitance for high-speed data transmission, a fast response time, and a low reverse leakage current. Its breakover and reverse breakdown voltages make it suitable for use on a range of devices. It has become an increasingly popular choice of component for TVS-diode applications due to its range of features and its ability to protect sensitive circuitry.
