DESCRIPTION
The SMP400G-BB is a Silicon P.I.N. photodiode
incorporated in a compact, 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 0.005" on a pitch of 0.1". The cathode of the
photodiode is electrically connected to the package.
The photodiode structure has been optimised for high
sensitivity, high speed 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 and
optional screening mesh ensure a rugged device with a
high degree of immunity to radiated electrical interference.
