SMCJ90C: TVS - Diodes Application Field and Working Principle

Over the past few years, the technology of transient voltage suppression (TVS) diodes has taken off, and a number of new products have come to the market. One of the most popular products – the SMCJ90C – is a glass-passivated junction, surface-mount TVS device designed for transient overvoltage protection. It is capable of protecting sensitive electronics against destructive voltage transients that occur in harsh industrial or automotive environments, as well as in normal household appliances. This article will discuss the application field and working principle of the SMCJ90C.

Application Field

The SMCJ90C is primarily used in a variety of automotive applications, from start/stop systems to infotainment systems. As a result, the SMCJ90C is often found on electronic boards in cars and trucks. On the industrial side, it is used in drive systems, inverters, and electronic switchgears. Additionally, it is used in consumer electronics, such as cell phones and laptops, as well as in medical and military applications.

Working Principle

The SMCJ90C TVS diode is designed to protect sensitive electronics against overvoltage or high energy surges. It works by quickly conducting high current away from a component to help limit the voltage that is applied to it. When a voltage spike above the breakdown voltage is applied to the device, the internal collision between electrons causes a large current to flow. This current is then conducted away from the device, providing protection to the component it is connected to. The SMCJ90C is a unidirectional device, meaning that it only passes current in one direction. It has an integrated TVS diode, as well as a junction termination. This junction termination absorbs the strain energy of the surge current, allowing no current to flow through the connected component. The SMCJ90C also has a metal oxide varistor, which absorbs and dissipates excess energy that is created during the surge or surge event.

Conclusion

The SMCJ90C is a popular transient voltage suppression (TVS) diode that is widely used in automotive, industrial, consumer electronics, medical, and military applications. It is designed to quickly conduct high current away from sensitive electronics, providing protection against high energy surges. The SMCJ90C has two major components: an integrated TVS diode and a junction termination. Additionally, it also contains a metal oxide varistor which helps absorb and dissipate excess energy.
