  • Publication number: 20100302693
    Abstract: The present invention provides a technique capable of realizing an ESD protection performance having a high ESD withstand voltage in a small layout area. An ESD protection circuit includes a clamping circuit, Zener diodes, a transistor comprised of a DMOS, a transistor comprised of an IGBT, and resistors. The ESD protection circuit effectively protects the protected circuit such that the transistor comprised of the DMOS is caused to absorb the current noise at the time of operating the protected circuit to prevent malfunction due to latchup and the IGBT (the transistor comprised of IGBT) whose current absorption capacity is increased by the thyristor effect is operated in parallel for a large current at the time of ESD.
