The electrical terminations are via two leads of diameter 0.018" on a pitch centre diameter of 0.2". The can structure incorporates an photoptic response optical filter with peak transmission at 510nm. The cathode of 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 photodiode active area provides asymmetric viewing angles in two orthogonal directions. The photodiode structure has been optimised for high sensitivity, asymmetric light measurement applications. The metal can and optional screening mesh ensure a rugged device with a high degree of immunity to radiated electrical interference.
