Optocoupler/LED/nixie tube/photoelectric device

This general-purpose optocoupler contains a gallium arsenide infrared light-emitting diode that drives a silicon phototransistor in a 6-pin dual-row plug-inencapsulation.

This general-purpose optocoupler includes a GaAs infrared emitting diode driving a silicon phototransistor within a six-pin dual-row plug-inencapsulation.

The 6N135M, 6N136M, HCPL4503M, HCPL2530M, and HCPL2531M optocouplers consist of an AlGaAs LED optically coupled to a high-speed phototransistor. A separate connection for photodiode biasing reduces the base-collector capacitance of the input transistor and is orders of magnitude faster than conventional phototransistors. The HCPL4503M has no internal connection to the phototransistor base, improving noise immunity. Internal interference shielding with excellent common-mode rejection up to 50,000 V/µs.
