Optocoupler/LED/nixie tube/photoelectric device

The MOC223M consists of a Gallium Arsenide Infrared Emitting Diode optically coupled to a monolithic silicon phototransistor detector in a small surface mount plastic encapsulation. The MOCD223M is a dual-channel version of the MOC223M. It is suitable for high-density applications without the need for through-board mounting.

The FOD420, FOD4208, FOD4216, and FOD4218 devices consist of an infrared light-emitting diode coupled to a hybrid random-phase triac consisting of two antiparallel SCRs with a triac capable of driving a discrete triac. terminal triac function. The FOD4216 and FOD4218 use high-efficiency infrared LEDs for higher trigger sensitivity. These devices use a standard 6-pin dual-inline plug-in (DIP) encapsulation.

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.
