P.I.N. PHOTODIODE
DESCRIPTION
The SMP525G-EJ 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 permits a wide range
of optical filter options. The cathode of the photodiode is
electrically connected to the package.
The photodiode active area provides asymmetric viewing
angles in two orthogonal directions. The photodiode
structure has been optimised for high sensitivity,
asymmetric light measurement applications. The metal can
and optional screening mesh ensure a rugged device with
a high degree of immunity to radiated electrical
interference.
