DESCRIPTION
Anode
The SMP400G-CD is 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 taller can
structure affords a greater range of optical filter options.
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. The
moderate viewing angle facilitates easy alignment of the
device with on-axis illumination sources. 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.
