Abstract
An electrostatic discharge protection device includes a clamping bipolar junction transistor and at least one electrostatic discharge circuit coupled between a first-voltage rail and a second-voltage rail. The electrostatic discharge circuit includes a silicon-controlled rectifier and a diode. The anode and the cathode of the silicon-controlled rectifier are respectively coupled to an I/O port and the first-voltage rail. The cathode of the diode is coupled to the anode of the silicon-controlled rectifier and the I/O port. The anode of the diode is coupled to the second-voltage rail. The absolute value of the reverse breakdown voltage of the diode is greater than the absolute value of the anode-to-cathode trigger voltage of the silicon-controlled rectifier, which is greater than the absolute value of the trigger voltage of the clamping bipolar junction transistor.
