TVS - Diodes are solid-state overvoltage protection devices that act as the main interface between the equipment and its power source. The SA12C-E3/73 is a very popular device in this category of components. This TVS diode offers a high level of protection for reactive circuits and protects against transient overvoltages in all applications where high-frequency transients (lightning strikes, motor start-ups, inductor excitations, etc.) are present.

The SA12C-E3/73 is a multi-function diode device with excellent performance. It is composed of a single unidirectional diode, along with two reverse zener diodes specially designed to offer excellent short-circuit protection, over voltage protection (OVP), reverse voltage protection (RVP), and over-current protection (OCP) for both AC and DC applications. This TVS diode features double surge protection and excellent clamping capability, making it attractive for use in various systems.

The working principle of the SA12C-E3/73 is simple and straightforward. In most applications, it is connected in parallel to the system under protection.
