SFH6156-3 Optocoupler IC (Phototransistor Output) – Hitachi

MPN:SFH6156-3

The SFH6156-3 is a high-reliability optocoupler IC from Hitachi, featuring an infrared LED input optically coupled to a phototransistor output. It provides excellent galvanic isolation between input and output, protecting sensitive low-voltage circuits from high-voltage spikes, noise, and ground loops.

With stable current transfer ratio (CTR) and fast response, the SFH6156-3 is widely used in industrial control, SMPS feedback, PLC I/O isolation, and signal interfacing applications.
