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 ABSOLUTE MAXIMUM RATINGS 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. 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.
