The VE17M00421K from FCPH series is a bidirectional, asymmetrical, 180Vrms rated, radial lead, service entrance style AC Power Line Surge Protective Device (SPD). It features high peak current capability, excellent energy absorption and superb protection from transient lightning, spikes and surges on AC power lines. It components have a low capacitance, providing very fast response times to transients.

The VE17M00421K has two areas of application: 1) it works by diverting high-powered surges away from sensitive electronic equipment, and 2) it provides protection on a variety of AC power lines. Both applications are very important in ensuring the protection of personnel, equipment, and facilities from damage by electrical transients.

The VE17M00421K is a type of TVS (Transient Voltage Suppressors), also known as MOVs (Metal Oxide Varistors). It is essentially composed of two distinct elements: one is the semiconductor structure, and the other is an ac protective device. The elements are connected in series. Typically, the configuration of the VE17M00421K is a series connection of a zinc-oxide varistor and silicon diode.

The varistor element is made from zinc oxide particles. These particles are held together in a matrix by pressure and electrical energy, and act as a resistor in the transmission of current. During normal operation, the electrical current passes through the zinc oxide element. When a high transient voltage is sensed, the element begins to clamp and divert the current away from the sensitive electronic components.

The second component of the VE17M00421K device is the silicon diode. During normal operation, the diode allows the current to pass through the zinc oxide element relatively unimpeded. However, the diode acts as a barrier during transient conditions, limiting the current flow. Thus, it provides additional protection against over-voltage and current issues on AC power lines.

The VE17M00421K is an extremely efficient and reliable surge protection device. It has excellent energy absorption and peak current capability, enabling it to handle surges in excess of 10,000A. It also features low capacitance, providing fast response times to transients. In addition, it is designed for service entrance applications, utilizing top-of-line components and a radial lead style. The VE17M00421K is the perfect choice for any surge protection application.
