TVS (Transient Voltage Suppressor), or MOV (Metal Oxide Varistor), are available in many sizes, shapes, and configurations, and they are designed to protect electronics circuits from the impact of transient voltage. One type of TVS is the SMF17A Resettable Varistor. This device is designed to have a high level of capacitance and low leakage current, which makes it suitable for use in a wide range of applications, including automotive, industrial, medical, telecommunications and consumer electronics.

The SMF17A RVG (Resettable Varistor) is a surface mount device (SMD) and is designed to protect circuit components from overvoltage transients. The device is capable of handling voltages up to 33 VDC with a minimum peak reverse current of 5mA. It is constructed of a special material that is designed to absorb a large amount of energy and store it for later release, thus safeguarding the device and the other components of the circuit from damage due to surges or spikes. The device is available in many different sizes, ranging from 0.5mm x 0.5mm to 3mm x 3mm, and is designed to be operationally stable over the temperature range of -40°C to 125°C.

The functioning of an SMF17A RVG is based on the principle of capacitive energy absorption. The device uses the external circuit’s applied voltage to charge two internal capacitors. The stored energy in the capacitors is then released as a surge, helping to reduce the peak voltage. This reduces the risk of damage to the device or adjacent components.

SMF17A RVGs are designed for use in a wide range of applications, including automotive, consumer electronics, industrial, medical, and telecommunications. They are well-suited for use in portable devices and appliances, as well as in other places where transient voltage protection is needed, such as AC power lines. In automotive applications, SMF17A RVGs can be used as transient voltage suppressors, or to protect electrical systems from power surges due to lightning strikes.

The SMF17A RVG is an excellent choice for providing a high level of transient voltage protection. The device is capable of absorbing large amounts of energy, and its low leakage current allows it to be used in many different applications. Its small size and wide temperature range make it an ideal choice for use in portable devices and automotive applications. Overall, the SMF17A RVG is a reliable, cost-effective solution for protecting electronic circuits from the damaging effects of transient voltage.
