SWITCHING CIRCUIT, AND DIODE

摘要

PROBLEM TO BE SOLVED: To provide a switching circuit which can be conducted bidirectionally by preventing the occurrence of latchup by a parasitic thyristor since there is a matter that the latchup arises in the parasitic thyristor contained in a transistor carrying a switching function in the conventional switching circuit which can perform a bidirectional conduction. SOLUTION: The switching circuit includes a MOS transistor carrying a switching function, a parasitic diode which exists in a source and a drain of the MOS transistor, and a diode connected in parallel with them.
