• Fiber-optic sensing

The SD290-12-22-241 can be used in these applications due to its high accuracy, fast response time, and low power consumption. It also has a low dark-current and excellent ambient light rejection ratio, making it ideal for applications that require accurate detection of light signals.

Working Principle:

The SD290-12-22-241 works by converting light photons into an electrical current. The diode consists of an active region flanked by two electrodes. When exposed to light, the active region of the photodiode absorbs the photons, resulting in an increased current flow between the two electrodes. This change in current flow can be used to measure the intensity of the light photons.

The SD290-12-22-241 is also capable of operating in reverse bias mode. In this mode, the diode acts as a barrier to current flow. When photons strike the active region, they create electron-hole pairs, which are then swept away by an increased electric field. This creates a voltage drop across the photodiode, which can be measured to calculate the intensity of the light.

The SD290-12-22-241 is capable of detecting light within a wide spectrum, from visible light to near-infrared. It also has a wide dynamic range and high signal-to-noise ratio, making it perfect for applications that require accurate measurement of light intensity.

In summary, the SD290-12-22-241 photodiode is an excellent optical sensor that can be used in a variety of applications. It has a wide dynamic range, excellent ambient light rejection, and a low dark-current, making it the perfect choice for applications that require accurate measurement of light signals.
