Optical sensors are devices that use the light energy in a specific wavelength range to measure objects in a non-contact manner. Phototransistors are a category of optical sensors that measure the intensity of light in photodetectors. One of the most commonly used devices in this category is the SFH 3505 phototransistor, which is an opto-electronic device that measures light intensity and converts it into electrical signals.

The SFH 3505 phototransistor is a p-n-p structure with an integrated photodiode and an integrated pre-amplifier. It is designed to be used in a wide range of applications, such as optical isolators, optical receivers, optical touch buttons, optical jog dials, and position sensors. It is also suitable for use in industrial automation, security systems, communications, instrumentation, and medical systems.

The SFH 3505 phototransistor has a wide operating range, from -40C to + 85C, and is capable of controlling light from visible to near-IR. It has a wide spectral response range, from 430nm to 1050nm. It is also capable of detecting low-level light intensity at up to 400 mA/m2 and can handle large levels of ambient illumination. Furthermore, it has a low supply current (1020mA) and a high gain of 50kV/mA.

When exposed to light, the SFH 3505 phototransistor’s integrated photodiode generates photocurrent, which is then amplified by the pre-amplifier. The output voltage from the pre-amplifier is then regulated by the integrated regulator and then fed to the output stage, where it is converted into an analog voltage. This voltage is proportional to the intensity of the light.

The SFH 3505 phototransistor has a wide range of applications. It has been used, for example, as an opto-coupler to transfer electrical signals in security systems and medical equipment, as an opto-sensing device in industrial and automotive applications, and as an optical receiver in communications systems. Additionally, it can be used as an ambient light sensor for automotive and home applications, such as streetlight control.

The SFH 3505 phototransistor is an ideal choice for a wide variety of applications due to its wide range of operating temperature and wide spectral response range. Furthermore, its low supply current and high gain make it an efficient and cost-effective solution for opto-electronic and sensing applications. As an integrated device, it is also easy to use and install, making it an attractive choice for a wide variety of applications.
