Abstract
An apparatus of preventing ESD and EMP coupled between a signal input and a signal output is provided with a first diode of forward bias including a positive terminal and a negative terminal connected to the signal input and ground respectively; and a first diode of reverse bias including a negative terminal and a positive terminal connected to the signal input and the ground respectively. The semiconductor is a diode including a p-type semiconductor region made of semiconductor material having a predetermined band gap and an n-type semiconductor region made of semiconductor material having a predetermined band gap. The predetermined band gap is greater than 3 eV. The diode operates in forward bias to discharge current generated by ESD and/or EMP. A method of preventing ESD and EMP is also provided.
