Optocoupler/LED/nixie tube/photoelectric device

The QSB363 is a silicon phototransistor with black infrared transparent T-3/4 encapsulation.

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 FOD8001 is a 3.3V/5V high-speed logic gate optocoupler that supports isolated communication, enabling digital signals to be communicated between systems without conducting ground loops or hazardous voltages. It utilizes ON Semiconductor's proprietary coplanar encapsulation technology Optoplanar and optimized IC design to achieve high noise immunity with high common-mode rejection and power supply rejection specification characteristics. This high-speed logic gate optocoupler encapsulation contains a high-speed AlGaAs LED driven by a CMOS buffer IC coupled with a CMOS sense IC in a small 8-pin encapsulation. The detection IC contains an integrated photodiode, a high-speed transimpedance amplifier, and a voltage comparator with output driver. This CMOS technology coupled with high efficiency LEDs enables low power consumption combined with very high speed (40ns propagation delay, 6ns pulse width distortion).
