Optocoupler/LED/nixie tube/photoelectric device

The MOC3071M, MOC3072M, and MOC3073M consist of a GaAs infrared light-emitting diode optically coupled to a non-zero crossing silicon triac (triac). These devices isolate low voltage logic from the 240 VAC line and provide random phase control of high current triacs or thyristors. These devices feature enhanced static dv/dt capability to ensure stable switching performance for inductive loads.

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.
