Since its initial launch in the late 1990s, the SMP12-E3/85A has become a popular choice for protecting sensitive electronic components from high voltage transients. Featuring a variety of features, including an adjustable triggering voltage, the SMP12-E3/85A has become a popular choice for equipment manufacturers throughout the world.

The SMP12-E3/85A belongs to the class of TVS (Transient Voltage Suppression) diodes. Essentially, a TVS diode is designed to protect sensitive electronics components from high voltages, such as electrostatic discharge (ESD) or lightning induced power surges. The SMP12-E3/85A was specifically designed to protect automotive and industrial systems from transient voltages and electric inductive spikes. It is capable of suppressing transient voltages up to 12V, while also providing a high surge capability of up to 30A.

The working principle of SMP12-E3/85A is based on the dual characteristics of the diode itself. When low level transient voltages are encountered, the diode functions as an efficient low-resistance (low Rds) closed-loop. In other words, the diode is acting like a closed circuit when a transient voltage is present. When the voltage exceeds a predetermined threshold, the diode switches into an open-state, clamping the voltage to the predetermined level. By protecting against transient voltages, the SMP12-E3/85A can provide reliable and effective protection to sensitive electronic components.

The SMP12-E3/85A can be used in a variety of applications, including telecommunications, automotive, industrial, military and aerospace. The diode can be used in power line protection applications, such as in lightning surge protection circuits, as well as in ESD protection circuits. In addition, the SMP12-E3/85A can be used to provide high levels of immunity to other transient voltages, such as motor starting spikes and power line switching spikes.

The SMP12-E3/85A is a versatile and reliable choice for protecting sensitive electronic components. With its adjustable triggering voltage, the diode can be used in a variety of applications that require high levels of immunity to transient voltages. Additionally, the SMP12-E3/85A is designed to provide reliable and effective protection in challenging environments. As such, it is an excellent choice for manufacturers who need to protect their equipment from transient voltage spikes.
