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.
