<p><P>PROBLEM TO BE SOLVED: To provide a photo-relay in which a MOSFET capable of satisfying both of a low on-state resistance and a high withstand voltage as well as achieving a small output capacitance (C(gd), etc.) is used. <P>SOLUTION: This MOSFET comprises a light emitting element to which a switching controlled input signal is supplied, a photovoltaic element which receives light emitted from the light emitting element and generates direct electric power, a drain electrode, and a source electrode, and a gate electrode to which an output voltage generated by the photovoltaic element is supplied. In a photo-relay using the MOSFET, the output voltage of the photovoltaic element supplied to the gate electrode of the MOSFET is made to be equal to or higher than a withstand voltage between the source and drain electrodes. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
