Optical Sensors - Photodiodes

The SFH 203 application field and working principle is an optical sensor specifically designed for use in photodiodes. It uses an integrated signal amplifier for fast and stable operation in order to provide a precise measurement of the irradiance of photosensitive surfaces. The SFH 203 is typically used in high accuracy measuring applications where ambient light is absent or needs to be minimized.

The SFH 203 is a very sensitive and cost-effective solution for light sensing applications. It can be used for measurements ranging from UV to near infrared light with a wavelength range of 270nm to 1000nm. The device offers a wide dynamic range of 1µA to 1mA. It also features a low power consumption of just 30µW. The device comes in an industrial grade package and features a low current temperature coefficient.

The SFH 203 works by measuring the irradiance of a light source and converting the current output into an accurate voltage level. It utilizes a PIN photodiode which signals the intensity of the incident light and the amplifier converts this measured current into a voltage. The SFH 203 is then able to accurately measure the intensity of the incident light and output the signal as a voltage level for further processing by the user.

The photodiode offers a fast response time resulting in less than 2msec measurement error. It also features high accuracy which is measured in the region of 3.5%. The device also has a typical temperature coefficient of 3ppm/°C, meaning it is highly reliable in temperature ranges of -25°C to 65°C.

The SFH 203 is a versatile and highly reliable solution for light sensing applications. It can be used in a wide range of applications, such as environmental monitoring, security systems, industrial automation, display backlights, and lighting control. The device is also suitable for safety applications due to its reliability and accuracy in detecting and responding quickly to light changes.

The SFH 203 is a highly reliable solution that offers superior performance in numerous applications. It is a cost-effective, highly accurate, and fast-responding light sensing device that is suitable for use in both commercial and industrial applications. The device is easy to install and requires minimal maintenance, making it an ideal solution for light sensing applications.
