Si PIN photodiode


High reliability, Large photosensitive area (5 × 5 mm), Stick packing


The S7478 series are PIN photodiodes having a large photosensitive area (5 × 5 mm) and surface mount flat package with leads. There are two same products in different packing types; the S7478 is reel packing and the S7478-02DS is stick packing.
