TVS - Diodes are an important component in the electronical world, and the SMAJ18CHE3/61 is one such solution that plays a significant role in applications which require protection from over voltage transients.

The SMAJ18CHE3/61 is an 18 volt, bi-directional unidirectional TVS diode and is ideal for protecting electronic systems from a variety of over-voltage threats such as inductive load switching, lightning strikes, ESD, and surge. As a transient voltage suppressor diode it is capable of withstanding reverse leakage current of 10 µA max. It is optimal for use in high-speed switching and high-voltage applications.

The SMAJ18CHE3/61 is a bilateral diode, which means it will suppress surges in either direction, and has a fast response time of 1 ns min. It offers excellent protection from transients up to 1500 watts peak power with a peak pulse current of 90 A. It is UL recognized, RoHS compliant, and meets all safety and environmental compliance standards.

The SMAJ18CHE3/61 provides effective protection in industrial and consumer applications, such as telecommunications, LED lighting, broadband cables, computers, and digital audio equipment. It works by absorbing the transient energy of a surge and dissipating it as heat. When a surge greater than the rated threshold occurs, the device will clamp the surge voltage and limit the peak current, thus providing protection.

Its working principle is simple and straightforward. During normal operations, the device behaves like an open circuit; allowing current to flow freely. When a surge occurs, the diode will become active and immediately reduce the peak voltage between the terminals by absorbing current as necessary. The transient is then diverted and dissipated through a low-resistance semiconductor path. This action prevents the destruction of components in the circuit by excessive voltage or current, thus providing protection.

In summary, the SMAJ18CHE3/61 is an effective, reliable and easy to use TVS diode designed for use in applications with high levels of electro-magnetic interference. It provides effective protection from over-voltage transients and is perfect for industrial and consumer applications for protecting against lightning strikes, ESD, and other forms of power surges. The device is easily installed in any electronic circuitry requiring protection from such electrical disturbances.
