摘要： A limiter for controlling an overvoltage and an RFID tag having the same are provided. The limiter includes a first limiter part and a second limiter part serially connected to the first limiter part. The second limiter part has at least one limit diode whose threshold voltage is lower than that of elements in the first limiter part. Accordingly, if an overvoltage is input, the limiter can maximize the input current drop so that the limiter can maximize the leakage voltage. As a result, the RFID tag can prevent the RFID driving part from being damaged due to the overvoltage. In addition, the RFID tag can normally operate regardless of the intensity of the driving voltage input from the RFID reader, so that the yields of products can improve.
