DESCRIPTION
The SMP550G-FJ is a Silicon P.I.N. photodiode
incorporated in a hermetic metal can package. The
electrical terminations are via two leads of diameter 0.018"
on a pitch centre diameter of 0.2". The can structure
permits a wide range of optical filter options. The
photodiode is electrically isolated from the package, which
has a separate earth lead.
The larger photodiode active area provides greater
sensitivity than the SMP400 range of devices, with a
corresponding reduction in speed. The photodiode
structure has been optimised for high sensitivity, light
measurement applications. The metal can, isolated
photodiode and optional screening mesh ensure a rugged
device with a high degree of immunity to conducted and
radiated electrical interference.
