P.I.N. PHOTODIODE
DESCRIPTION
The SMP550G-FL 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
incorporates an photoptic response optical filter with peak
transmission at 510nm. The cathode of the photodiode is
electrically isolated from the package, which has a
separate earth pin.
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 and optional
screening mesh ensure a rugged device with a high
degree of immunity to radiated electrical interference.
