4N25 IC Opto coupler ONSEMI DIP-6 4N25

Product Overview

The 4N25 is a single-channel phototransistor optoisolator that optically couples an infrared LED to a silicon phototransistor with an accessible base terminal. It establishes a high electrical isolation barrier of 5,300 Vrms to safely separate low-voltage control logic from high-voltage circuits. The device features a maximum output voltage of 30V, a 100 mA maximum forward current, and typical 2 µs switching times. It is packaged in a standard 6-DIP housing and serves as a reliable interface for power supplies, logic circuits, and industrial controllers.
