Abstract
A semiconductor device which can achieve high breakdown voltage and high ESD tolerance of a current drive output terminal at the same time, and can quicken the response speed of a current flowing through the current drive output terminal. The inventive semiconductor device is provided, between the current drive output terminal and a first transistor or a low breakdown voltage element, with a second transistor having a breakdown voltage higher than that of the first transistor or that of the low breakdown voltage element. Furthermore, the inventive semiconductor device is provided with a diode having an anode connected with a path between the first transistor or the low breakdown voltage element and the second transistor, and a cathode connected with an ESD protection circuit.
