The Isocom 4N25 is a general-purpose optocoupler featuring a phototransistor output in a 6-pin dual in-line package (DIP). It utilises a gallium arsenide infrared LED optically coupled to a silicon NPN phototransistor, providing electrical isolation between input and output. With an isolation voltage of 5000 VRMS, it ensures safe signal transmission across different voltage domains. The device offers a current transfer ratio (CTR) of 20% minimum at a forward current of 10 mA. Its typical rise and fall times are 3 µs, making it suitable for medium-speed switching applications.
The Isocom 4N25 optocoupler stands out due to its high isolation voltage, ensuring safe operation in environments with significant voltage differences. Its compact 6-pin DIP package allows for easy integration into various electronic circuits. The device's fast switching times and reliable performance make it perfect for applications that require efficient signal isolation and noise suppression.
