Handling and Safety Precautions
Anti-static
protection, such as ionized air blowers
or grounded wrist straps with a 1 mega series
resistor, should be used at all
times when
handling laser diodes. In addition, soldering irons
should be well grounded.
Overheating caused by
soldering of the leads of a
laser diode must be prevented. Recommend
soldering iron temperature and maximum
exposure time are below 260 OC and 10 seconds.
Description
The MCD-3P4C-312 is InGaAs
PIN photodiode
which has a sensitive area of ∅∅75um
.The small
photosensitive region will enable operation at low
dark current and low capacitance,
and yet large
enough to allow efficient coupling to multi-
mode
fiber .
This product is designed for
high speed and low
noise applications and is suited to receive the light
source from 1000~1600 nm.
The MCD-3P4C-312
is compatible with industry
standard wave or hand solder processes.
