The electrical terminations are via two leads of diameter 0.018" on a pitch of 0.2". The can structure incorporates an optical filter that only transmits infra-red light. 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. The metal can and optional screening mesh ensure a rugged device with a high degree of immunity to radiated electrical interference.
