DESCRIPTION
The SMP550G-EM 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 of 0.2". The can structure incorporates an optical
filter that only transmits infra-red light. The cathode of the
photodiode is electrically connected to the package.
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.
