Abstract
A TVS circuit having a first diode with a cathode coupled to a first terminal and an anode coupled to a first node. A second diode has an anode coupled to a second node and a cathode coupled to a third node. A third diode is coupled between the first node and second node. A fourth diode is coupled between the first node and third node. A fifth diode is coupled between the second node and a second terminal. A sixth diode is coupled between the second terminal and the third node. A seventh diode can be coupled between the second terminal and an intermediate node between the fifth diode and sixth diode. The first diode is disposed on a first semiconductor die, while the second diode is disposed on a second semiconductor die. Alternatively, the first diode and second diode are disposed on a single semiconductor die.
