Optocoupler/LED/nixie tube/photoelectric device

The FOD2742 opto-isolated amplifier consists of the popular KA431 precision programmed shunt reference and optocoupler. The optocoupler is a gallium arsenide (GaAs) light emitting diode optically coupled to a silicon phototransistor. It has 3 levels of reference withstand voltage = 2%, 1% and 0.5%. Current transfer rate (CTR) ranges from 100% to 200%. It also has an excellent temperature coefficient of 50 ppm/°C. It is primarily used as an error amplifier/reference voltage/optocoupler function in isolated AC-DC power supplies and DC-DC converters. When using the FOD2742, power supply designers can reduce component count and save space in compact encapsulation designs. The tight tolerance range reference eliminates the need for adjustment in many applications. The device is available in an 8-pin small outline encapsulation.

The MOC303XM and MOC304XM devices consist of an AlGaAs 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 of equipment powered from the 115V AC line, such as teletypewriters, CTRs, solid state relays, industrial controls, printers, motors, solenoid valves, and consumer equipment.

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 provides excellent common-mode rejection up to 50,000 V/µs.

The FOD8163 series is a 3.3 V/5 V high-speed logic gate optocoupler with open collector output that supports isolated communication, enabling digital signals to be communicated between systems without conducting ground loops or hazardous voltages. The FOD8163 series utilizes tensile body encapsulation to achieve 8 mm creepage and spacing (FOD8163T) and optimized IC design for reliable high isolation voltage and high noise immunity. The FOD8163 series consists of Aluminum Gallium Arsenide (AlGaAs) Light Emitting Diodes with integrated high speed photodetectors. The output of the sense IC is an open-collector Schottky clamp transistor. Its electrical and switching characteristics are guaranteed over the extended industrial temperature range of -40°C to 100°C and a VCC range of 3 V to 5.5 V.
