DESCRIPTION
The SMP550G-FN is a Silicon P.I.N. photodiode
incorporated in a lensed, hermetic metal can package. The
electrical terminations are via two leads of diameter 0.018"
on a pitch centre diameter of 0.2". 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 narrow viewing angles
provide better coupling to on-axis illumination sources. 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.
