Optocoupler/LED/nixie tube/photoelectric device

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 FOD2743 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 reference voltage tolerance levels: 2%, 1% and 0.5%. Current Transfer Ratio (CTR) ranges from 50% to 100%. 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 FOD2743, power supply designers can reduce component count and save space in compact encapsulation designs. The tight tolerances eliminate the need for adjustment in many applications. The device features an 8-pin DIP white encapsulation.

The FOD8480 and FOD8482 are low-power optocouplers that support isolated interfaces for Intelligent Power Modules (IPMs), transferring digital control signals from the controller to the IPM without conducting ground loops or hazardous voltages. The FOD848x family is a stretched body, 6-pin small plastic enclosure containing a gallium aluminum arsenide (AlGaAs) light emitting diode and an integrated high gain integrated high gain photodetector. The detector has a detector threshold with hysteresis. Hysteresis provides differential mode noise immunity, eliminating the possibility of output signal chatter. Its non-inverting output is designed as a totem pole and does not require any pull-up resistors. The FOD8482 has a low threshold input current IFLH of 3.0 mA maximum. The electrical and switching characteristics of the full FOD848x family are guaranteed over the extended industrial temperature range of -40°C to 100°C and a VDD range of 4.5 V to 30 V. Low IF and wide VDD range, compatible with TTL, LSTTL, and CMOS logic levels, and lower power consumption than other high-speed optocouplers.

The FOD8314 series is a 1.0 A output current gate drive optocoupler for driving medium power IGBT/MOSFET. It is ideal for fast switching driving power IGBTs and MOSFETs used in motor control variable frequency applications as well as high performance power systems.
