SFH551/1-1 SFH551/1-1V Integrated Photo Detector Receiver for Plastic Fiber Plastic Connector Housing Data Sheet Description Features The SFH551/1V is a transimpedance amplifier with digital • Bipolar IC with open-collector output TTL open collector output stage and integrated photodi- • Digital output, TTL compatible ode. The active area of the detector in connection with the molded microlens gives an efficient coupling from • Sensitive in visible and near IR range the end of a plastic fiber. • Low switching threshold The receiver is fully DC coupled and therefore no line • Transfer rate ≤ 5 Mbit/s code is needed. • 2.2 mm aperture holds standard 1000 micron plastic The SFH551/1V includes a Schmitt trigger function to fiber provide stable output states over the whole dynamic • No fiber stripping required range. For optical input power levels above 6 μW typically • Molded microlens for efficient coupling the electrical output will be logical “low” and vice versa. With noise free Vcc and GND no undefined output signal Plastic Connector Housing is possible. SFH551/1 must not be used without shielding the ambient light, because ambient light causes malfunc- • Mounting screw attached to the connector tion when reaching the threshold level, noise or complete • Interference-free transmission from light-tight switching the output. Interference free transmission is housing possible by using the SFH551/1V with the black plastic • Transmitter and receiver can be flexibly positioned connector housing. • No cross talk • Auto insertable and wave solderable Ordering Information • Supplied in tubes Type Ordering Code SFH551/1-1 SP000063860 Applications SFH551/1-1V SP000063855 • Household electronics • Power electronics • Optical networks
