Optocoupler/LED/nixie tube/photoelectric device

The FOD2711A opto-isolated amplifier consists of the popular AZ431L precision programmed shunt reference and optocoupler. The optocoupler is a gallium arsenide (GaAs) light emitting diode optically coupled to a silicon phototransistor. The reference voltage tolerance is 1%. Current Transfer Ratio (CTR) ranges from 100% to 200%. It is primarily used as an error amplifier/reference voltage/optocoupler function in isolated AC-DC power supplies and DC-DC converters. When using the FOD2711A, power supply designers can reduce component count and save space in compact encapsulation designs. The tight tolerance range reference eliminates the need for adjustment in many applications. The device features an 8-pin DIP white encapsulation.

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.
