MF446 750 - 850 nm, 1.5 GHz PIN Photodiode Data Sheet September 2004 Ordering Information MF446 MF446 MF446 MF446 MF446 MF446 ST SMA FC SC PT TO-46 Package ST Housing SMA Housing FC Housing SC Housing Pig-Tail including 1m of 62.5/125 m multi-mode fiber -40 C to +85 C Note:The rated Responsivity applies to all options. Features * * * 750-850 nm PIN Photodiode 1.5 GHz Bandwidth Designed for Single-mode and Multi-mode Fiber 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 100 mm without loss in responsivity and a reverse voltage of only 3.3 Volts makes interfacing to a preamplifier easy. Applications * * * * * Fast Ethernet Fibre Channel 1x, 2x Gigabit Ethernet Infiniband General Purpose CATHODE ANODE CASE ANODE CATHODE Bottom View The diode chip is isolated from the case.
