The SFH551/1-1 is a photodetector to be used with 1000 micron plastic optical fiber. This device amplifies incoming signals via a DC coupled trans-impedance amplifier, and its open collector output is TTL compatible. The SFH551/1-1 includes a Schmidtt trigger function to provide stable outputs over the entire dynamic range. This helps prevent false data signals due to noise on the power supply or ground line. The SFH551/1-1 comes in a T13/4 plastic package with a tubular aperture wide enough to accomodate fiber and cladding. The SFH551/1V-1 is housed in a unique plastic right angle package for easy coupling between the fiber and the photodetector. The SFH551/1V-1 is suitable for data communication uses such as: LANs, medical equipment, and automotive electronics.
