P.I.N. PHOTODIODE

DESCRIPTION

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.
