The 07D431K is a “surface mount” type varistor manufactured by SOCAY. The device is designed for applications requiring transient voltage protection, surge protection, and EMI filtering. This varistor is suitable for use in electronic designs requiring a wide range of voltage protection, from 350-710V and currents up to 1.2KA. Its small profile makes it suitable for use in applications where space is a premium, such as mobile phones, tablets, and other small portable devices. The device is constructed of zinc oxide, and has RoHS compliant materials.
