Optical sensors are used in many applications because of their ability to detect light and other forms of electromagnetic radiation. Phototransistors are one type of optical sensor which uses a light-sensitive transistor. This type of sensor is particularly useful in measuring light levels or for detecting the presence of a light source. The BPX 85 phototransistor is a highly sensitive optical detector used in a variety of applications and is becoming increasingly popular due to its low power consumption and reliability.

The BPX 85 is a two-terminal, small outline integrated circuit packaged with a built-in phototransistor. It has a low-level sensitivity of 5 mW/cm2 with an operating voltage of 1.2 VDC and a power dissipation of 1 mW. The phototransistor is based on a high-gain photo-detector element designed to be sensitive in the visible spectrum and is engineered for excellent photoconductivity. This allows it to detect small amounts of light and respond quickly to changes in light levels.

One of the most common applications for the BPX 85 phototransistor is in optical switching systems. It can be used to detect the presence or absence of light to control an electrical switch. For example, it can be used in automatic door openers or to detect motion. The phototransistor can be used to detect light from any source such as infrared sensors or light emitting diodes. In addition, the BPX 85 can be used in smoke detectors to detect the presence of particles of smoke in the air.

The working principle of the BPX 85 phototransistor is based on the photoconductive effect. This occurs when electrons in the base region of the transistor become excited by the incident light wave. The excited electrons can then move across the base region and into the collector region. This creates a potential difference across the base emitter junction which is then amplified by the transistor. This amplified signal is then used to control the switching system or other device.

The BPX 85 is ideal for applications that require low power consumption, high sensitivity, and precise response times to changes in light levels. It is also extremely reliable and can tolerate a wide range of environmental conditions. Due to its compact size, it is ideal for use in a range of different applications.

In conclusion, the BPX 85 phototransistor is an extremely useful and reliable optical detector which can be used in a wide variety of applications. It is particularly useful for optical switching systems as it is capable of detecting small amounts of light and responding quickly to changes in light levels. It is also highly reliable and can tolerate a wide range of environmental conditions. Its low power consumption and compact size make it an ideal choice for many applications.
