摘要： A transient voltage suppression device includes at least one diode string, a power clamp device, at least one first bypass diode, and at least two second bypass diodes. The diode string is coupled between a power terminal and a common bus and coupled to an input output (I/O) port. The power clamp device is coupled between the power terminal and the common bus. The first bypass diode is coupled between the common bus and a ground terminal The second bypass diodes are coupled in series, coupled between the common bus and the ground terminal, and coupled to the first bypass diode in reverse parallel. Alternatively, the first bypass diode and the second bypass diodes are replaced with at least one bi-directional electrostatic discharge (ESD) device.
