TIL116 Optocoupler with Transistor Output 30V 5mA DIP-6
The TIL116 is an optically coupled isolator consisting of a gallium arsenide infrared emitting diode and a high-current transfer ratio silicon NPN phototransistor mounted in a plastic dual-in-line package. This design allows for electrical isolation between the input and output circuits, protecting sensitive control electronics from high voltages, ground loops, and noise on the output side. It is commonly used to interface logic signals between systems operating at different voltage potentials or to provide a safety barrier in power supply and motor control circuits. With its ability to handle continuous input current and provide a clean, amplified output signal, the TIL116 serves as a robust solution for digital logic interfacing and AC mains detection.
This optocoupler is characterized by its high direct-current transfer ratio, ensuring efficient signal transmission with minimal input drive. The device’s construction ensures stable performance across a wide range of humidity and temperature conditions, while its high-voltage electrical isolation makes it suitable for industrial and consumer applications requiring safety certification. The phototransistor output can switch loads up to 30 volts, making it compatible with TTL/CMOS logic and various microcontroller inputs. For applications needing to switch higher power loads, the TIL116 is often used to drive a separate power transistor or relay.
