TVS (Transient Voltage Suppressors) diodes are a type of protective device designed to protect an electronic circuit or equipment from voltage transients, which are very short duration, high-energy electrical pulses. They are commonly used in power and communication applications, such as power supplies, surge protectors, and automotive electronics. SMP12-M3/85A is a type of TVS diode that is designed to protect circuits from high-voltage transients.

The SMP12-M3/85A is a small device measuring 1.25mm x 1.3mm x 0.6mm and is made using a silicon-bismuth alloy. It is a unidirectional device and consists of two terminals, an anode and a cathode, which have to be connected in the opposite direction for proper operation. The SMP12-M3/85A is able to protect circuits from transients in the voltage range of 3.3V to 17V, with a maximum clamping voltage of 18V. It also features a reverse breakdown voltage of 12V and a maximum surge current of 85A.

The working principle of SMP12-M3/85A is based on the movement of charge carriers, or electrons, which move through a semiconductor material when a voltage is applied. In the case of the SMP12-M3/85A, the semiconductor material is made of a silicon-bismuth alloy and the electrons move through channels within the material. When a transient voltage is applied, the electrons are caused to move to the anode terminal and accumulate, creating an electric field. This electric field creates a barrier, which prevents the transient voltage from reaching the protected circuit.

The SMP12-M3/85A is a very useful device for providing protection from a variety of transients. It is suitable for a wide range of applications, including telecommunications, computers, consumer electronics, automotive and industrial electronics. It can be used in a variety of ways, such as providing protection from surge currents, high frequency noise, AC and DC transients, and overvoltage events. It is also suitable for high-speed, low-impedance applications such as Ethernet, USB, and data communication systems. Because it is small and inexpensive, it is an ideal choice for many surface mount designs.

The SMP12-M3/85A is an important component for protecting circuits from high-voltage transients. It is a low-cost, reliable, and easy to use device that can provide the necessary protection for a variety of applications. Its small size and low cost make it an ideal choice for surface mount designs, while its high surge current capability makes it suitable for a variety of applications. It is a reliable and efficient device, which provides a high level of protection for electronic circuits and equipment.
