The FCI-InGaAs-300B1XX from OSI Optoelectronics are Back-Illuminated InGaAs Photodiode/Arrays that have a spectral range of 900 to 1700 nm. They have an active area diameter of 300 μm and a pitch of 500 μm with a minimum responsivity of 0.8-0.85 A/W. These photodiodes are designed to be flip chip mounted to an optical plane for front or back illumination. They can be mounted traditionally (active area facing up) or assembled face down minimizing the overall dimensions. These photodiodes have a minimum bandwidth of 100 MHz with 8 pF capacitance and a dark current of 0.05 nA. They have a minimum breakdown voltage of 10 V and a maximum forward current of 25 mA. These photodiodes are available as a single element diode or 4/8-elements array and are ideal for high speed optical communications, multichannel fiber optic receiver, power monitoring, single/multi-mode fiber optic receiver, fast ethernet, SONET/SDH OC-3/STM-1, ATM, instrumentation and analog receiver applications.
