Fea tures
• Low cost plastic cap package
• Designed to self align in the 0.228
diameter bore of standard fiber optic
receptacles
• Press fit simplifies component
installation
• Optimized for fiber optic applications
using 50 to 200 micron fiber
De scrip tion
The OPF520 contains a monolithic
photo-IC comprised of a photodetector
and DC amplifier driving an open
collector output Schottky transistor. The
output makes the OPF520 compatible
with TTL and CMOS logic.
The receiver is designed to operate from
a single +5 V supply. It is essential that
a bypass capacitor be connected from
VCC to Common of the receiver.
