SFH551/1-1 and SFH551/1-1V
Receiver with Digital Output Stage
for Polymer Optical Fiber Applications
Data Sheet
Description
Features
The SFH551/1-1 receiver is a transimpedance amplifier
with an integrated photodiode and TTL open-collector
output stage. The active area of this detector combined
with the molded microlens gives an efficient coupling
from the end of the polymer optical fiber. This receiver
enables data rates up to 5 MBd and works with the Avago
SFH757 transmitter diode.

Digital output, full TTL compatible
Sensitive in visible and near IR range
Transfer rate ≤ 5MBd
Low switching threshold
2.2mm aperture holds standard 980/1000/2200μm
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.

Plastic Direct Fiber Connector housing (V-housing)
With noisefree Vcc and GND, an undefined output signal
is not possible. Nevertheless, the SFH551/1-1 must not
be used without shielding from ambient light. If ambient
light could reach the threshold level, the SFH551/1-1V

housing of the SFH V-series shields the ambient light
perfectly.
No cross talk
Auto insertable and wave solderable
SFH series components are optimized for easy coupling.
Supplied in tubes
No fiber stripping is required; just insert the cut fiber into
the selected SFH component.

a pre-amplifier. A differential amplifier is connected in
series and works as a post-amplifier. Its output is passed
to the internal Schmitt trigger that drives a bipolar NPN
transistor. The data-out signal is from the collector of this
bipolar transistor.
SFH551/1-1V
The V-housing allows easy coupling of unconnectorized
2.2 mm polymer optical fiber by an axial locking screw.
The SFH551/1-1 receiver is a transimpedance amplifier
with a TTL open-collector output stage, therefore a
pull-up resistor of at least 330 Ω is necessary (see Figure
1). To minimize interference a bypass capacitor (100 nF)
must be placed near (distance ≤ 3 cm) the SFH551/1-1
ports. In critical applications a shorter distance is better.

Package V-housing mounting pins
SFH V-series components have two pins that are electri-
cally isolated from the inner circuit. The pins are only
designed for mounting the V-housing to the PCB surface.
This helps increase stability, which is needed during
fixing the fiber end by the axial locking screw.

The retention force between the soldered mounting pins
and the V-housing of the SFH component is about 20 N
(with a vertical exertion of force). This is an approximate
value.
