DESCRIPTION
The SMP525G-FK is a Silicon P.I.N. photodiode incorporated
in a hermetic metal can package. The package window has
greater ultra-violet light transmission, thus extending the useful
spectral range of the device. The electrical terminations are via
two leads of diameter 0.018" on pitch centre diameter of 0.2". The
photodiode is electrically isolated from the package, which has a
separate earth lead.
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 across the infra-red to ultra-violet spectrum. Inclusion
of a suitable optical filter into the package can produce a device
that responds only to ultra-violet light. 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.
