DESCRIPTION
1
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.
TO-39 Package
Pin 1 – Anode
Pin 2 – Cathode
Pin 3 – Case
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.
