MF446
High-Performance PIN
Description
The very high speed and low capacitance of this
GaAs PIN Photodiode makes it ideal for datacom and
general purpose applications. Its double-lens optical
system collects power from fibers with up to 100mm
without loss in responsivity and a reverse voltage of
only 3.3 Volts makes interfacing to a preamplifier
easy.
