FPT530 phototransistors equivalent, hermetic to-18 silicon phototransistors.
two pins are used (collector and emitter pins). The availability of the base pin gives wide latitude for flexible circui.
FPT51 0 I FPT530 I FPT550 are nitride-passivated npn Planar silicon phototransistors. These devices are packaged in a TO-18 style, hermetically sealed package with lens cap. For most applications two pins are used (collector and emitter pins). The av.
