L14G2 - Phototransistor (Equivalent - L14F1 / L14G3)

L14G2 NPN Phototransistor - Light Sensor (L14F1/L14G3 Equivalent)

The L14G2 is an NPN phototransistor for light detection. It functions as a photodetector, converting incident light into an electrical response. This component is utilized in sensing applications, often paired with an LED light source. Its transparent case exposes the base-collector region, optimizing light sensitivity. Inherent current gain amplifies the resulting photocurrent. The L14G2 conducts in the presence of light and remains off in its absence. It has a maximum dark current of 100nA and a light current of 500µA. This phototransistor is a direct equivalent for L14F1 and L14G3 in most circuit designs.
