SMT Quadrant Photodiode Incorporates Large Active Area

The PSS-QP50-6-SM surface-mount quadrant photodiode has a total active area of 50 mm², and the quadrant features an element gap of 42 µm. Capacitance per quadrant is typically 17 pF at 12V of bias. Spectral responsivity is 0.45 A/W at 633 nm with a rise time of 45 ns. Dark current is less than 10 nA per segment at 10V. The overall package measures 14.5 mm x 16.6 mm and is 2.2-mm thick. A clear non-darkening resin protects the device and surface mounting can be accomplished by re-flow soldering or by using conductive epoxy.
