Optocoupler/LED/nixie tube/photoelectric device

The H11AAXM series consists of two GaAs infrared emitting diodes connected in anti-parallel to drive a single silicon phototransistor output.

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.

The 6N138M/9M and HCPL2730M/31M ​​optocouplers consist of an AlGaAs LED optically coupled to a high gain split Darlington photodetector. The split Darlington configuration separates the input photodiode and first-order gain from the output transistor, allowing for lower output saturation voltage and faster operation than conventional Darlington optocouplers. In the dual-channel devices HCPL2730M/HCPL2731M, the integrated emitter-base resistor has excellent stability over temperature. The combination of an extremely low input current of 0.5mA and a high current transfer ratio of 2000% makes this series ideal for use as an input interface for MOS, CMOS, LSTTL and EIA RS232C, while ensuring output compatibility to CMOS and high fanout TTL requirements. Internal interference shielding with excellent common-mode rejection of 10 kV/µs.
