Abstract: Overvoltage protection circuits are provided. In some embodiments, an overvoltage protection circuit includes a first diode made of a first semiconductor material having a bandgap width greater than that of silicon. A second diode is included and is electrically cross-coupled with the first diode. The second diode is made of a second semiconductor material different from the first semiconductor material.

Abstract: A control circuit for controlling a first transistor includes a diode for suppressing transient voltages. A cathode of the diode is coupled to a first conduction terminal of the first transistor, and an anode of the diode is coupled to a first node. A first resistor is coupled between the first node and a control terminal of the first transistor. A second transistor has a control terminal coupled to the first node, a first conduction terminal configured to receive a first supply voltage, and a second conduction terminal coupled to the control terminal of the first transistor.
