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 of 0.2". The cathode of the photodiode is electrically connected to the package. 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 across the infra-red to ultraviolet spectrum. Inclusion of a suitable optical filter into the package can produce a device that responds only to ultraviolet light. The metal can and optional screening mesh ensure a rugged device with a high degree of immunity to radiated electrical interference.
