TVSs or transient voltage suppressors are semiconductor devices designed for restricting high voltage transients to protect circuitry from destruction. MOV or metal oxide varistors, are a type of TVS and are designed to protect low or medium voltage circuits from overvoltage transients.

In this article, we will discuss the ROV20-471K and its application field and working principle. The ROV20-471K is a bidirectional TVS transient voltage suppressor diode with an operating voltage range of 5.7 to 200 volts. This device features low clamping voltage and excellent surge absorption characteristics and is capable of transient absorption of up to 25A peak. The ROV20-471K can also handle up to 5,000V of ESD protection, making it an ideal choice for a wide variety of applications.

The ROV20-471K is designed for use in automotive, industrial and consumer applications, such as: automotive computers and related systems, electronic control units, DC power systems, power supplies, LCD panels, and audio/video equipment. The device is also suitable for EMI mitigation in circuit designs and for protecting circuits against fast transients and other high voltage overshoots. It can even protect circuits from lightening strikes and electrostatic discharges.

The ROV20-471K’s working principle is based on a voltage diversion principle which can effectively divert transient voltage away from the protected circuit. This is accomplished via a metallized junction between the diode and the two leads, which are connected in series with the device. When an overvoltage surge is present, the METAL plate embedded in the junction allows the voltage to be divided between the two leads and diverted away from the circuit, reducing its effect.

In summary, the ROV20-471K is a TVS device that features low clamping voltage, excellent surge absorption characteristics, and tremendous ESD protection capabilities. It is designed for use in a wide variety of automotive, industrial, and consumer applications, and is capable of diverting overvoltage transients away from protected circuits. This makes it an ideal choice for protecting both analog and digital electronic circuits from electrical overstress and other voltage spikes.
