Optocoupler/LED/nixie tube/photoelectric device

The QSE113/114 is a silicon phototransistor featuring a wide angle, IR transparent, black plastic sidelooker enclosure.

The FOD2741 opto-isolated amplifier includes the popular KA431 precision programmable shunt voltage 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 voltage with tolerance = 2%, 1% and 0.5%. The range of current transfer ratio (CTR) is 100%-200%. It also has an outstanding temperature coefficient of 50 ppm/°C. It is primarily used as an error amplifier/reference voltage/optocoupler in isolated AC-to-DC power supplies and DC/DC converters. When using the FOD2741, power supply designers can reduce the number of components and save space in tight encapsulation designs. Tight tolerance references make adjustments unnecessary in many applications. The device features an 8-pin DIP white encapsulation.

The FOD3125 is a 2.5 A output current gate drive optocoupler capable of driving medium power IGBT/MOSFET up to 125°C. It is suitable for fast switching drive of power IGBTs and MOSFETs used in motor control inverter applications and high performance power systems. It utilizes ON Semiconductor's coplanar encapsulation technology Optoplanar and optimized IC design to achieve high noise immunity with high common-mode rejection specified characteristics. It consists of a gallium aluminum arsenide (AlGaAs) light-emitting diode optically coupled to an integrated circuit with a high-speed driver for a push-pull MOSFET output stage.

The 6N137M, HCPL2601M, HCPL2611M single-channel and HCPL2630M, HCPL2631M dual-channel consist of an 850 nm AlGaAS LED optically coupled to a very high-speed integrated photodetector logic gate with tunable output. This output has an open collector allowing a wired OR output. Coupling parameters are guaranteed from -40°C to +85°C. Input signals up to 5mA provide a minimum output sink of 13mA (fan-out 8). Internal interference shielding provides excellent common-mode rejection, typically 10kV/µs. The HCPL2601M and HCPL2631M have a minimum CMR of 5kV/µs. The minimum CMR of the HCPL2611M is 10kV/?s.
