Optocoupler/LED/nixie tube/photoelectric device

The MCT6X optocouplers have two channels for density applications. For quad-channel applications, two encapsulations are used to accommodate standard 16-pin DIP sockets. Each channel is an NPN silicon epitaxial planar phototransistor optically coupled to a gallium arsenide light-emitting diode.

The FOD420, FOD4208, FOD4216, and FOD4218 devices consist of an infrared light-emitting diode coupled to a hybrid random-phase triac consisting of two antiparallel SCRs with a triac capable of driving a discrete triac. terminal triac function. The FOD4216 and FOD4218 use high-efficiency infrared LEDs for higher trigger sensitivity. These devices use a standard 6-pin dual-inline plug-in (DIP) encapsulation.
