Abstract

PURPOSE:To make optical thyristor conducting at voltages not exceeding a desired voltage through optical signal by a simple circuit configuration according to an optical thyristor and an enhancement type MOSIGFET. CONSTITUTION:Where an electric signal is applied to an input signal circuit 1 so as to have anode side of a luminous diode 5 at (+), the luminous diode 5 gives an optical signal to P gate optical thyristors 6 and 8. In case X terminal voltage is (+) and its value is effective enough to make a source-drain circuit of IGFET 9 conducting, the optical thyristor 7 gets in conduction. Where Y terminal is on (E) potential, the optical thyristor 8 and IGFET 9 become conductive at low voltages according to the optical signal.
