Based on type, the global silicon phototransistors market can be divided into normal silicon phototransistor and Darlington silicon phototransistor.This results in poor conversion efficiency of phototransistors.ĭarlington Silicon Phototransistor Segment Witnesses Significant Growth Potential Also, the material used in a phototransistor may limit its voltage-handling capability, for instance, silicon cannot handle voltage of over 1,000 volts and the efficiency of phototransistors decreases when an electromagnetic field interferes the operational area.However, silicon phototransistors do not have a particularly good high-frequency response, which is restraining the market to a certain extent. Phototransistors offer several advantages, such as lower noise levels, over their alternatives such as avalanche photodiodes.Silicon phototransistors are also rapidly used for system control in automotive applications, including hybrid and electric vehicles.The Darlington silicon phototransistor segment held the maximum market share, in terms of value, in 2018.Photodiodes convert light into photocurrent much quicker than phototransistors, which limits the demand for the latter for use in high-speed applications. Another key challenge for the global silicon phototransistors market is that phototransistors are sluggish compared to photodiodes.Furthermore, rising use of silicon phototransistors in the lighting industry is driving the global market for silicon phototransistors, as these phototransistors are largely used in ambient light sensing and street light sensing.Increasing adoption of sensors has been driving the global phototransistor industry, as phototransistors are used as position sensors.Key Drivers and Restraints of Global Silicon Phototransistors Market Silicon phototransistors are widely used in different electronic devices for detecting light, for example, infrared receivers, smoke detectors, lasers, and CD players.have the same basic radiation frequency response.
In fact, all diodes, transistors, Darlington transistors, triacs, etc. All silicon photosensors (phototransistors) respond to the entire range of visible radiation as well as to infrared rays.
