DESCRIPTION
The SMP400G is a Silicon P.I.N. photodiode specifically designed for optical fibre communication. The device is incorporated in a compact, low profile, hermetic metal can package. A glass bead lens incorporated into the TO-46 case provides an efficient optical design. This affords substantial mis-alignment between the device and a fibre optic cable without degrading the coupling efficiency.
