TVS - DiodesTransient voltage suppression (TVS) diodes are semiconductor devices specifically designed to protect sensitive electronic equipment from voltage transients induced by electrical surges. They are an individual component used in the construction of electronic devices and circuits. Different types of these diodes can also be used to protect data lines, such as Ethernet and USB, from power surges.The SAC18-E3/73 is a surge-stabilizing diode, specifically designed to protect against transient overvoltage. It has a maximum peak surge-current capacity of 20kA, which is ideal for medium-high performance applications such as dome cameras, surveillance cameras, and industrial automation equipment.The SAC18-E3/73 is a unidirectional device, which means it will only conduct when the voltage is applied in one direction and has no effect in the other. It works by using an on-state resistance of 40 milli-ohms and a fast response to transient events. When the voltage exceeds a certain point, the diode is turned on and the current is diverted away from the sensitive electronics, dissipating the surge energy and thus protecting the circuit from potential damage.Given its 20kA maximum peak surge-current capacity, the SAC18-E3/73 is suitable for many different applications, such as RV/boat motor electronics, industrial equipment, LED lighting, communications equipment, IT and home entertainment equipment, consumer electronics, and automotive applications. As such, it is ideal for medium-high performance applications such as dome cameras, surveillance cameras, and industrial automation equipment.In terms of its working principle, the SAC18-E3/73 uses reverse bias protection to shield against voltage transients. When a surge hits the diode, the reverse-biased junction quickly turns on and allows current to flow in one direction only. This flow of current works to lower the voltage while providing a much faster response than a traditional Zener diode.The SAC18-E3/73 also has several features that make it attractive for consumers. It has a low on-state resistance of just 40 milli-ohms, with a wide operating range and a useful temperature range of -40°C to 105°C. Additionally, it has a low parasitic inductance and low capacitance, which makes it ideal for use in high-speed applications.In conclusion, the SAC18-E3/73 is a unidirectional TVS diode that is designed to protect sensitive electronics from voltage transients induced by electrical surges. It has a maximum peak surge-current capacity of 20kA, which makes it suitable for many different applications. The SAC18-E3/73 also has several features that make it ideal for medium-high performance applications such as dome cameras, surveillance cameras, and industrial automation equipment. Finally, the SAC18-E3/73 works using reverse bias protection to shield against voltage transients.
