The OP245PS is an 850 nm, infrared emitting diode molded in IR transmissive amber-tinted epoxy packages. It features a point source irradiance pattern, wavelength matched to silicon’s peak response, fast switching speed, and a side-looking package for space limited applications. It is ideal for use in PC board mounted slotted switches or as easily mounted interrupt detectors. Its stable VF vs. Temperature characteristic makes it suitable for applications where voltage is limited, and its low tr/tf makes it ideal for high-speed operations.
