DESCRIPTION
Cathode
and case
Anode
The SMP550G-EN 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 of 0.2". 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 narrow viewing angles
provide better coupling to on-axis illumination sources. The
metal can and optional screening mesh ensure a rugged
device with a high degree of immunity to radiated electrical
interference.
