Abstract
Provided is a transient voltage suppression device including a power supply terminal, a ground terminal, a Zener diode, a diode string, and an isolation device. The Zener diode is coupled between the power supply terminal and the ground terminal, and a node is between the Zener diode and the power supply terminal. The diode string has a first terminal, a second terminal, and an input/output (I/O) terminal. The second terminal is coupled to the ground terminal. The isolation device is coupled between the node and the first terminal. When an abnormal current flows through the isolation device and an energy of the abnormal current per unit time exceeds a preset value of the isolation device, the isolation device blocks a path of the abnormal current.
