1.5SMC18AT3 is mostly used in the field of Transient Voltage Suppressor Diodes (TVS). This device is well suited for general purpose applications in order to protect circuits from transient voltage. The working of the 1.5SMC18AT3 device is based on a simple principle. It basically acts to suppress voltages above a pre-determined level.

The 1.5SMC18AT3 is designed to protect against temporary voltage surges that are typically seen in power distribution, telecommunications and telecom equipment, consumer electronics, data processing, and industrial equipment. It also helps to protect electrical components from over-voltage situations that can lead to failure. The device provides protection against transients from common causes like lightning and electrostatic discharges. It also provides protection from power line and inductive spikes.

The device consists of a diode which acts as a break-down element, and a resistor which acts as a current limiter. When the voltage on the input exceeds the clamping voltage, the diode conducts and the resistor limits the current through it. This action is known as snapback, and it is the primary feature of the 1.5SMC18AT3 TVS diode. The current limiting function of the 1.5SMC18AT3 helps to protect sensitive components against voltage spikes.

The 1.5SMC18AT3 device provides a clamping voltage of 18V, and it has a peak pulse power rating of 1500 Watts. Its operating range extends from -55 to +150 °C. It is packaged in a small, thermally-enhanced SMA (Surface Mount Assembly) package which makes it suitable for applications requiring compactness and high thermal performance.

The 1.5SMC18AT3 is used in a variety of applications, such as power and telecom equipment, computers, consumer electronics, automotive and industrial applications. This device is designed to provide reliable protection against transient voltages for a wide variety of applications. With its high peak pulse power and reliable performance, it has been nicknamed "the robust protector".
