SFH309FA PHOTOTRANSISTOR NPN 900NM 3MM SFH309FA

The SFH309FA is a high-sensitivity NPN phototransistor designed to detect infrared (IR) radiation with a peak sensitivity at 900nm. Encapsulated in a compact 3mm package, this phototransistor is ideal for a wide range of applications including remote controls, light barriers, object detection, and optical sensors. Its small size allows for easy integration into space-constrained designs while maintaining excellent performance. The SFH309FA is designed to be sensitive to light in the near-infrared spectrum, with a peak sensitivity at 900nm. This wavelength is commonly used in remote control applications and other IR-based systems. The NPN transistor configuration allows for easy interfacing with standard electronic circuits.

When IR radiation strikes the phototransistor, it generates a current that is proportional to the intensity of the light. This current can be amplified and processed to detect the presence or absence of IR radiation. The 3mm package provides a compact and robust housing for the phototransistor. Its small size makes it easy to integrate into a variety of applications, while its durable construction ensures reliable operation in harsh environments. The SFH309FA features a wide viewing angle, allowing it to detect IR radiation from a variety of angles. This is particularly useful in applications where the source of IR radiation may not be perfectly aligned with the phototransistor.

The device also features a low dark current, which minimizes noise and improves the accuracy of the measurement. The SFH309FA is commonly used in applications such as remote controls, where it is used to detect the IR signals transmitted by the remote. It is also used in light barriers, where it is used to detect the presence or absence of an object. Other applications include object detection, optical sensors, and ambient light sensing.
