The electrical terminations are via three leads of diameter 0.008" on a pitch centre diameter of 0.1". 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 structure has been optimised for high sensitivity, high speed light measurement applications. The wide viewing angle provides relatively even reception over a large area. 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.
