P.I.N. PHOTODIODE

DESCRIPTION

The SMP525G-FL 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 photoptic response optical filter with peak

transmission at 510nm. The cathode of 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

and optional screening mesh ensure a rugged device with

a high degree of immunity to radiated electrical

interference.
