Phototransistors are considered as the photodiode attached to an amplifiers that are integrated on a single silicon chip. As the phototransistors produce higher current than the photodiodes, they are preferred for many applications. Current parameter not being the only reason, but also the voltage generation which was not like the photoresistors, which became a point for the selection of phototransistors over others.
The increasing adoption of sensors has been driving the demand of phototransistor industry as phototransistors are used as position sensors. Further, the increasing use of phototransistors in the lighting industry is also surging the demand for this market as phototransistors are largely used in ambient light sensing and street light sensing. Phototransistors, as compared to other alternatives such as avalanche photodiodes, offer several advantages, such as lower noise levels.
