Phototransistors have several important advantages that separate them from other optical sensors. For example, phototransistors produce a higher current than photodiodes while also being able to produce a voltage, something that photoresistors cannot do. Phototransistors are very fast and are capable of providing nearly instantaneous output. Phototransistors are relatively inexpensive, simple, and small enough to fit several of them onto a single integrated computer chip.

It depends on the phototransistor's design. Most are normally open until you shine light on them.
In the designation L14G1 phototransistor, the "L" typically stands for "light," indicating that it is a light-sensitive device. The "G" often represents "germanium" or "glass," referring to the material used in the phototransistor's construction or packaging. The "14" and "1" are likely specific model numbers or series identifiers used by the manufacturer to differentiate this phototransistor from others in their lineup.

All bipolar transistors are light sensitive: photons striking the semiconductor create electron-hole pairs which make the transistor conduct.In ordinary transistors this is an undesirable source of noise, so they are packaged in opaque metal or plastic cases.A phototransistor on the other hand is packaged either in a metal case with a transparent lens or in transparent plastic to let light in.Note: this is not a significant effect with MOS transistors.

A photo interrupter module for a smoke alarm has a gallium-arsenide infrared LED and silicon phototransistor that is contained in a plastic housing. When smoke interrupts the slot between the receiver and sender, the module is switched on.
