PC917NP is an excellent optoelectronic device designed to provide high-speed detection capabilities in various types of systems. It is used in a wide range of applications, including sensing applications, optical data transmission, medical systems, and energy-efficient systems.PC917NP is a reflective type photocoupler that consists of an infra-red LED (Light Emitting Diode) and a NPN phototransistor as its main elements. It contains a sealed optical surface on the LED side and an exposed active surface on the phototransistor side. The light from the LED is transmitted to the phototransistor via a sealed optical path. The optical signal is converted to an electrical signal at the phototransistor side.The main application fields of PC917NP are in the areas of sensing, medical technology, optical data transmission, and energy efficiency. Its reflective type construction enables it to provide high speed detection capabilities in these areas. In sensing applications, PC917NP can be used to detect objects, position, velocity, rotate speed, incline tilt, and detect rotation for fully automated devices. In medical technology, it can detect tiny movements that occur during respiration and detect the change in light on the skin. In optical data systems, PC917NP can be used to detect changes in the light transmittance of optical fibres for high speed data transmission. In energy-efficient devices, it can help detect end of motion, speed, acceleration, and pulse width modulation for energy-efficient operation.The working principle of PC917NP is based on the basic phototransistor diode construction. When the Power Supply of the LED is on, it emits LED light to pass through the sealed optical path. At the other side, the layer facing the optical path is the sensitive surface of the phototransistor. The light which reaches the photosensitive surface excites the electrons to trigger a flow of electrons from the collector to the emitter, thus providing an electrical output. This is how optical signals are converted into electrical signals.The speed at which the detection takes place is largely determined by the drive voltage of the LED and the dark current of the phototransistor. At higher drive voltages, the LED emits more light and thus the corresponding detection time decreases. On the other hand, a higher dark current in the phototransistor makes the sensing faster.In conclusion, PC917NP is an excellent optoelectronic device with high-speed detection capabilities in various areas. Its main application fields are in sensing, medical technology, optical data transmission, and energy efficiency. Its working principle is based on optical to electrical signal conversion using the basic phototransistor diode construction. The speed of detection is determined by the voltage applied to the LED and the dark current of the phototransistor.
