SFH551V/1

The SFH551V/1 is a kind of transimpedance amplifier with digital TTL open collector output stage and integrated photodiode. It includes Schmitt trigger function to provide stable output states over the whole dynamic range. The typical applications include household electronics, power electronics and optical networks.

There are some features of SFH551V/1 as follows: (1) bipolar IC with open-collector output; (2) digital output, TTL compatible; (3) sensitive in visible and near IR range; (4) low switching threshold; (4) transfer rate 5 Mbit/s; (5) 2.2 mm aperture holds standard 1000 micron plastic fiber; (6) no fiber stripping required; molded microlens for efficient coupling.

What comes next is about the absolute maximum ratings of SFH551V/1. (1): VCC (supply voltage range without damage) is from -0.5 to 15 V; (2): recommended and guaranteed maximum voltage is 5.5 V; (3):  VCCmin (minimum supply voltage for function) is 4 V; (4): Routmin (minimum pull-up resistance(VCC=5 V)) is 330; (5): VO (output voltage) is from -0.5 to 15 V; (6): IO (output current) is 50 mA; (7): PD (power dissipation (output)) is 100 mW; (8): Tstg (storage temperature range) is from -40 to +100; (9): Top (operating temperature range) is from -40 to +85; (10): TS (soldering temperature (2 mm from case bottom, t 5 s)) is 260.
