DESCRIPTION
The SMP550G-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.
TO-39 Package
Pin 1 – Anode
Pin 2 – Cathode
Pin 3 – Case
The larger photodiode active area provides greater
sensitivity than the SMP400 range of devices, with a
corresponding reduction in speed. The photodiode
structure has been optimised for high sensitivity, 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.
