Description

The SFH756 is a low-cost transmitter for simple optical data transmission with polymer optical fiber. The 650nm LED allows for speeds up to 10MBd.

The transparent plastic package has an aperture where the the 2.2mm fiber-end can be inserted and fixed with glue. This easy coupling method is extremely cost-effective.

The SFH756 is a kind of plastic fiber optic transmitter diode. The typical applications include household electronics, power electronics, optical networks and light barriers.

There are some features of SFH756 as follows: (1) good linearity (forward current>2 mA); (2) 2.2 mm aperture holds standard 1000 micron plastic fiber; (3) no fiber stripping required; (4) molded microlens for efficient coupling.

What comes next is about the absolute maximum ratings of SFH756. (1): VR (reverse voltage) is 3 V; (2): IF (forward current) is 50 mA; (3): IFSM (surge current (t10 s, D=0)) is 50 mA; (4): Ptot (power dissipation) is 120 mW; (5): RthJA (thermal resistance, junction/air) is 450 K/W; (6): Tstg (storage temperature range) is from -40 to +100; (7): Top (operating temperature range) is from -40 to +85; (8): Tj (junction temperature) is 100; (9): TS (soldering temperature (2 mm from case bottom, t 5 s)) is 260.
