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 FODM301X, FODM302X and FODM305X series consist of a GaAs IR LED driving a silicon bidirectional switch in a compact 4-pin miniature flat encapsulation. Lead spacing is 2.54mm. Suitable for interfacing between electronic controls and power triacs to control resistive and inductive loads at 115V/240V.
