The TOSHIBA TLP3123 consists of a gallium arsenide infrared emitting diode optically coupled to a photo-MOS FET in a plastic SOP package. The TLP3123 is a bi-directional switch, which can replace mechanical relays in many applications. And its high on-state current maximum rating and low on-state resistance is suitable to control a power line.
