Abstract
A bidirectional electrostatic discharge protection device includes at least one bipolar junction transistor and at least one silicon-controlled rectifier. The silicon-controlled rectifier is coupled to the bipolar junction transistor in series. The absolute value of the breakdown voltage of the bipolar junction transistor is lower than that of the silicon-controlled rectifier and the absolute value of the holding voltage of the bipolar junction transistor is higher than that of the silicon-controlled rectifier when an electrostatic discharge voltage is applied to the bipolar junction transistor and the silicon-controlled rectifier.
