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