Optocoupler/LED/nixie tube/photoelectric device

The FODM121 series, FODM124 and FODM2701 include a Gallium Arsenide Infrared Emitting Diode driving a phototransistor within a compact 4-pin micro-flat encapsulation. Lead spacing is 2.54 mm. The FODM2705 consists of two Gallium Arsenide Infrared Emitting Diodes connected in anti-parallel for AC operation.

The FOD2741 opto-isolated amplifier includes the popular KA431 precision programmable shunt voltage reference and optocoupler. The optocoupler is a gallium arsenide (GaAs) light-emitting diode optically coupled to a silicon phototransistor. It has 3 levels of reference voltage with tolerance = 2%, 1% and 0.5%. The range of current transfer ratio (CTR) is 100%-200%. It also has an outstanding temperature coefficient of 50 ppm/°C. It is primarily used as an error amplifier/reference voltage/optocoupler in isolated AC-to-DC power supplies and DC/DC converters. When using the FOD2741, power supply designers can reduce the number of components and save space in tight encapsulation designs. Tight tolerance references make adjustments unnecessary in many applications. The device features an 8-pin DIP white encapsulation.
