Optocoupler/LED/nixie tube/photoelectric device

The HMHA281 and HMHA2801 series of devices include a GaAs infrared emitting diode driving a silicon phototransistor within a compact 4-pin micro-flat encapsulation. Lead spacing is 1.27 mm.

The MOC306XM and MOC316XM devices consist of a GaAs infrared light-emitting diode optically coupled to a monolithic silicon detector, performing the function of a zero voltage crossing double-sided triple driver. These devices are suitable for triacs in logic system interfaces from 115/240V AC line powered equipment such as solid state relays, industrial controls, motors, solenoid valves, and consumer equipment.

The HCPL05XX and HCPL04XX optocouplers consist of an AlGaAs LED optically coupled to a high-speed photodetector transistor in a compact 8-pin small-outline encapsulation. 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 HCPL04XX devices do not have a lead-bonded substrate for greater noise margin. Each encapsulation of the HCPL053X device has two trenches for optimum packing density.
