Optocoupler/LED/nixie tube/photoelectric device

The MOC3081M, MOC3082M, and MOC3083M devices consist of a GaAs infrared emitting diode optically coupled to a monolithic silicon detector, performing the function of a zero-voltage crossing double-sided triac driver. These devices can be used with discrete power triacs to interface logic systems with 240 VAC line-powered devices 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.

The OptoHiT FODM8801 is a new phototransistor utilizing ON Semiconductor's advanced proprietary process technology to achieve high operating temperature characteristics up to 125°C. This optocoupler consists of a gallium aluminum arsenide (AlGaAs) infrared light emitting diode (LED) optically coupled to a phototransistor in a compact half-pitch, miniature low-profile, 4-lead encapsulation. It provides high current transfer rate with very low input current. The input-output isolation voltage VISO is rated at 3750 VACRMS.
