Product Overview

The SFH551/1-1 is a 650nm Digital Receiver Diode for simple optical data transmission with polymer optical fibre. It incorporates a photo detector with integrated IC and provides a TTL output signal. The active area of this detector combined with the moulded micro-lens gives an efficient coupling from the end of the polymer optical fibre. This SP000063860 receiver enables data rates up to 5Mbaud and works with the Avago SFH757 transmitter diode. The SFH551/1-1 is fully DC coupled and therefore no line code is needed. The internal Schmitt trigger ensures stable output states over the whole dynamic range. If light with intensity above the threshold level is coupled into the SFH551/1-1, the electrical output will be logical "low" and vice versa. With noise free Vcc and GND, an undefined output signal is not possible. Nevertheless, the SFH551/1-1 must not be used without shielding from ambient light.
  • Auto insertable and wave solderable
  • Sensitive in visible and near IR range
  • No fibre stripping required
  • Moulded micro lens for efficient coupling
