DESCRIPTION
Anode
The SMP400G-CA contains a Silicon P.I.N. photodiode
incorporated in a compact, low profile, 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. The
wide viewing angle provides relatively even reception over
a large area. 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.
