Optical Sensors - Phototransistors

Optical sensors are devices which use light to detect the presence or absence of an object. Phototransistors are a type of optical sensor which employ the combination of a photovoltaic cell and a transistor to control a small current when exposed to light, making them useful in detecting the presence or absence of objects. The OP598B is an example of a phototransistor, designed for use in a variety of applications.

The OP598B is a dual-device containing a photodiode connected to a bipolar transistor. Its package is a small surface-mount device, making it suitable for applications requiring limited space. The device is sensitive to both infrared and visible light, with a range of spectral sensitivity from 450 nm to 1100 nm. The OP598B has a wide variety of applications and can be utilized in multiple areas, including alarm systems, light detection circuits, and dark/light detection systems.

The OP598B’s operating principle is based on the property of a PN junction diode, which can be directly utilized as a photodetector, allowing it to convert light energy into electrical energy. The device has two regions within it - an N-type and a P-type semiconductor. When exposed to light, each region creates electron-hole pairs, resulting in current flow. The photodiode produces a current which flows into the base of the connected transistor, thus controlling the current throughout the device.

The OP598B has two main modes of operation; current mode and voltage mode. In current mode, the transistor’s collector and emitter create a closed loop, allowing current to flow freely when exposed to light. In voltage mode, the junction diode function is used, resulting in a voltage being generated which allows for precise light detection. Furthermore, the OP598B has a low power consumption rate, a wide operating temperature range, and is immune to electrical interference, making it ideal for applications in harsh environments.

The OP598B is an ideal opto-electronic solution for a variety of applications due to its low power consumption, wide spectral operation range, and robust design. It is an ideal choice for applications in environments which require sensitive light detection, such as in security systems, robotics, and automotive lighting systems. The device’s low power consumption, wide operating temperature range, and immunity to electrical interference also make it an excellent choice for embedded solutions which require precise light detection or switching.
