DESCRIPTION

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 sig-

nals due to noise on the power supply or ground line.

The SFH551/1-1 comes in a T13/4 plastic package with a tubular aper-

ture 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.
