The electrical terminations are via two leads of diameter 0.018" on a pitch centre diameter of 0.2". The photodiode is electrically isolated from the package, which has a separate earth lead. 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 narrow viewing angles provide better coupling to on-axis illumination sources. 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. 3 2 1 TO-39 Package Pin 1 – Anode Pin 2 – Cathode Pin 3 – Case ABSOLUTE MAXIMUM RATINGS (Tcase = 25°C unless otherwise stated) Operating temperature range Storage temperature range Temperature coefficient of responsively Temperature coefficient of dark current Reverse breakdown voltage Semelab plc.
