Transient Voltage Suppressor (TVS) diodes are widely used in the protection of electronic circuits from overvoltage transients and voltage spikes, and are versatile and rugged enough to be used in a variety of applications. The SM15T18AHE3/9AT is one such device, a Unidirectional Transient Voltage Suppressor (TVS) diode that can provide surge protection up to 1500W peak pulse power per line for very short-duration transients.

The SM15T18AHE3/9AT is a highly integrated, low-cost device that offers overvoltage protection for high-voltage digital and analog circuits. The device consists of a monolithic substrate with a single p-type region and an array of three n-type termination regions. The p-type region is the cathode and the three n-type regions are the anodes, for a total of four terminals with the anode terminals connected together.

The SM15T18AHE3/9AT is designed to offer a low capacitance rating, high surge protection up to 1500 W peak pulse power per line, and low leakage current. It is a unidirectional device that blocks voltages up to 1800V, making it ideal for many applications, including: overvoltage protection in automotive, home and industrial electronics; overcurrent protection in automotive, home and industrial electronics; and ESD protection. Additionally, the device operates at a wide range of temperatures, making it suitable for hot environments.

The SM15T18AHE3/9AT uses a unique structure that is designed to protect the underlying circuit from voltage transients and spikes. The anode regions are formed as a single monolithic substrate, with a different internal structure than that found in traditional TVS diodes. This structure allows the device to be able to effectively absorb large surges, while also providing a very high capacitance rating.

The SM15T18AHE3/9AT is designed to work in unison with a system’s primary protection circuitry. When an overvoltage transient is detected, the device will activate, limiting the current and thus shielding the underlying circuitry from the spike or surge. In this way, the device can prevent damage to the underlying circuit from overvoltage transients.

The SM15T18AHE3/9AT is a highly integrated and versatile TVS diode that is ideal for a variety of applications. It offers low capacitance rating, high surge protection up to 1500W peak pulse power per line, low leakage current, and protection from overvoltage transients. Its wide range of temperature operation makes it well-suited for many types of environments. It is an excellent choice for providing reliable protection for a wide range of electronic systems and devices.
