P.I.N. PHOTODIODE
DESCRIPTION
The SMP400G-CB contains a Silicon P.I.N. photodiode
incorporated in a compact, hermetic metal can package.
The electrical terminations are via three leads of diameter
0.008" on a pitch centre diameter of 0.1". The photodiode
is electrically isolated from the package, which has a
separate earth lead.
The photodiode structure has been optimised for high
sensitivity, high speed light measurement applications
acrosss 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.
