Electrostatic discharge (ESD) is a very common cause of electrical system malfunction and component damage. It is caused by the movement of charges from a conductive object to a grounded object or vice versa and results in a powerful electrical current. In order to protect against ESD, devices designed to absorb or dissipate electrical energy, such as varistors and MOVs, are often used. The purpose of this article is to discuss the application field and working principle of the VE0805M101R002, an ESD protection varistor designed to protect against the effects of electrostatic discharge.

The VE0805M101R002 is a multilayer Variable Expulsion Varistor (VEV) device designed for ESD protection. It is a monolithic, single-terminal, surface mount device, encased in an SMD package and designed to be mounted on a printed circuit board (PCB). The device has an 8mm diameter and is approximately 0.35mm thick. In addition to its use in ESD protection circuitry, the VE0805M101R002 can also be used to protect against short-term voltage transients, such as those caused by power surges.

The VE0805M101R002 operates on the principle of variable expulsion protection. This is achieved by the combination of the properties of two materials: an Positive Temperature Coefficient (PTC) ceramic dielectric disc and an electrolytic medium. The PTC ceramic disc consists of a network of metallic particles and is comprised of two metal electrodes. The two electrodes are sandwiched between a ceramic layer and a resin layer that serves to form an electrolytic medium. The electrodes are connected to two terminals which are attached to the external circuitry.

When a voltage exceeding the specified ESD threshold value is applied to the VE0805M101R002, the metallic particles contained in the ceramic layer become polarized. This causes the particles to repel each other and, in the process, expel some of the electrolyte medium between them. This causes a reduction in the amount of current flow to the electrodes and thus, to the external circuitry, allowing for ESD protection.

The VE0805M101R002 is ideal for use in a variety of applications including consumer electronics, industrial equipment, automotive components, and military and aerospace applications. It has been primarily designed for use in low power applications under 10 W, in static active circuits and in dynamic switching circuits. The device is also capable of ESD protection from a variety of electrostatic sources such as charged material handling, electrostatic charge generated from workbenches, and external ESD events from a human being or an ESD simulator.

In conclusion, the VE0805M101R002 is a variable expulsion varistor device designed for ESD protection. It operates on the principle of variable expulsion protection, which is achieved by the combination of the properties of two materials: an Positive Temperature Coefficient (PTC) ceramic dielectric disc and an electrolytic medium. It is ideal for use in a variety of low power applications and is capable of providing ESD protection from a variety of electrostatic sources.
