Features: Epoxy package Linear response vs. irradiance Fast switching me Choice of wide or extra wide receiving angle Side-looker package Small package style ideal for space-limited applica ons OP955 Description: Each, and OP955 device consists of a PIN silicon photodiode molded in an epoxy packge that allows spectral response from visible to infrared light wavelengths. The side-looking package is designed for easy PCBoard moun ng and space-limited applica ons. The has a 95 wide receiving angle that provides rela vely even recep on over a large area and is mechanically and spectrally matched to OPTEK s GaAs and GaAiAs series of infrared emi ng diodes. The has a 8 very wide receiving angle that provides rela vely even recep on over a large area. The OP955 has a 95 wide receiving angle with a recessed lens, which allows an acceptance half-angle of 45 when measured from the op cal axis to the half power point. Both and OP955 components are 00% produc on tested, using infrared light for close correla on with OPTEK s GaAs and GaAIAs emi ers.
