The FOD410, FOD4108, FOD4116 and FOD4118 devices consist of an infrared emitting diode coupled to a hybrid triac formed with two inverse parallel SCRs which form the triac function capable of driving discrete triacs. The FOD4116 and FOD4118 utilize a high efficiency infrared emitting diode which offers an improved trigger sensitivity. These devices are housed in a standard 6-pin dual in-line (DIP) package.
“This project offers an extremely compact solution for interfacing 2 high voltage resistive or inductive loads. At a low profile, this is the most compact & versatile optically isolated 2 channel solid state relay system. The circuit consists of 2x Triacs …
