Optocoupler/LED/nixie tube/photoelectric device

The QTLP610CPD is a phototransistor with a miniature SMD encapsulation molded from water-clear plastic with a right-angle lens.

The FOD2711A opto-isolated amplifier consists of the popular AZ431L precision programmed shunt reference and optocoupler. The optocoupler is a gallium arsenide (GaAs) light emitting diode optically coupled to a silicon phototransistor. The reference voltage tolerance is 1%. Current Transfer Ratio (CTR) ranges from 100% to 200%. 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 FOD2711A, 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 features an 8-pin DIP white encapsulation.

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.

The HCPL4502M, HCPL4503M, HCPL2503M, 6N135M, 6N136M, HCPL2530M, and HCPL2531M optocouplers consist of an AlGaAs LED coupled to a high-speed photodetector transistor. By reducing the base-collector capacitance of the input transistor, a separate connection for photodiode biasing increases speed by several orders of magnitude over conventional phototransistor optocouplers. The HCPL4503M is not internally connected to the phototransistor base to help improve noise immunity, and the internal noise shield provides best-in-class common-mode rejection up to 50,000V/µs.
