TVS (Transient Voltage Suppressor), or MOVs (Metal Oxide Varistors), are one of the most common and important types of electronic components. They are used in a wide variety of electronic circuits and applications, from small electronic circuits to those powering large industrial machines. ROV20-121K-S is one type of these components. It is an automotive grade Transient Voltage Suppressor (TVS) for automotive applications. It is a low-clamping voltage, low capacitance TVS for protecting sensitive electronic equipment against the electrostatic discharges.
The ROV20-121K-S can help prevent damage due to overvoltage and electrical surges by providing a reliable clamping voltage and an appropriate surge current. It is designed for use in automotive applications, but it can also be used in general industrial applications. The device has a low leakage current and has a maximum surge current of 275A.
The ROV20-121K-S works by using a zener diode (or a pair of zener diodes) to clamp the voltage when the voltage rises above a certain level. When the voltage changes, the zener diode changes its resistance, leading to a reduction in the voltage reaching the sensitive components. This helps to limit the amount of current able to flow through the component, thus protecting it from damage. The device also has a current limit feature that can help limit the current drawn by the components.
The ROV20-121K-S is typically used in a variety of automotive applications, such as engine control units, high voltage power lines, electronic control units, solenoids, and various other components. It can also be used to protect components in industrial systems, such as motors, lighting systems, and HVAC systems from overvoltage and electrical surges.
In conclusion, the ROV20-121K-S is a versatile type of TVS/MOVs designed to protect sensitive electronic components from the damaging effects of overvoltage and electrical surges. It can be used in a variety of automotive and industrial applications, as it provides a low-clamping voltage and an appropriate surge current.
