P.I.N. PHOTODIODE
DESCRIPTION
The SMP600G-FK is a Silicon P.I.N. photodiode incorporated
in a hermetic metal can package. The package window has
greater ultra-violet light transmission, thus extending the useful
spectral range of the device. The electrical terminations are via
two leads of diameter 0.018" on pitch centre diameter of 0.2". The
photodiode is electrically isolated from the package, which has a
separate earth lead.
The larger photodiode active area provides greater sensitivity
than the SMP550 range of devices, with a slight reduction in
speed. Inherent in the device geometry is a reduction in the
receiving angle. The photodiode structure has been optimised for
high sensitivity, light measurement applications across the infra-
red to ultra-violet spectrum. Inclusion of a suitable optical filter
into the package can produce a device that responds only to
ultra-violet light. 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.
