FPT136 phototransistors equivalent, general-purpose silicon phototransistors.
involving pulsed or low duty cycle operations. 2. Measured at noted irradiance as emitted from a tungsten filament lamp .
The FPT131 and FPT136 are 3-terminal npn Planar phototransistors with exceptionally stable characteristics and high illumination sensitivity. The availability of the base pins gives wide latitude for flexible circuit design. The case is a special pla.
