WebJan 11, 2024 · The phototransistor is a junction semiconductor device similar to the photodiode in that it generates a current proportional to light intensity. It might be thought … WebA phototransistor is basically a photodiode with another junction added. This results in a light-sensitive solid-state unit that permits the transistor to be biased to detect a light …
WebJun 21, 2012 · 7. First move the LED to the transistor's collector, and add a series resistor. You now have a common collector circuit, and the 2N3904's base is at 2.7 V or higher, depending on the LED voltage. Then if there's no current through the phototransistor you have 300 μ A base current (0.3 V / 1 kΩ). WebAdvantages of Photo Transistor: The efficiency of this type of transistor is greater than a photodiode. The transistor’s current gain is also more compare to photodiode; even if …
WebAn infrared (IR) phototransistor is a transistor that can only trigger on with infrared light. How a phototransistor works is it has 2 terminals, an emitter and collector. It does not have a terminal connection to its base. The base is simply made up of infrared light-sensitive material. In a regular transistor, current or voltage needs to be ...
