Description
The L14F1 is a high-sensitivity silicon Photodarlington designed for precision optical sensing applications. Featuring a narrow-angle, hermetically sealed construction, this device is engineered to provide superior directional sensitivity and long-term environmental protection. Its Darlington configuration significantly increases gain compared to standard phototransistors, making it ideal for detecting low-intensity light signals in industrial and consumer sensing environments.
With an operating temperature range of -65°C to +125°C, the L14F1 is built for rugged performance in demanding conditions. Its narrow ±8° reception angle allows for focused detection, minimizing interference from ambient light sources. This through-hole component is a perfect choice for reliable, long-distance optical switching, light-beam detection, and high-gain sensing tasks.
