DESCRIPTION
The SMP525G-FM is a Silicon P.I.N. photodiode
incorporated in a hermetic metal can package. The
electrical terminations are via two leads of diameter 0.018"
on a pitch centre diameter of 0.2". The can structure
incorporates an optical filter that only transmits infra-red
light. The photodiode is electrically isolated from the
package, which has a separate earth lead.
The photodiode active area provides asymmetric viewing
angles in two orthogonal directions. The photodiode
structure has been optimised for high sensitivity,
asymmetric light measurement applications. 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.
