Common questions from engineers and buyers evaluating this part.
The 4N25 is used to isolate electrical signals between circuits while transferring signals via an infrared LED and a phototransistor. It is commonly used in power supply feedback, microcontroller interfacing, and digital logic isolation.
The 4N25 comes in a through-hole package, typically a 6-pin DIP (Dual Inline Package). This package is suitable for PCB mounting and provides ease of handling and replacement.
The 4N25 has a lifecycle status of 'Transferred', which means production has been transferred to another manufacturing site. It may still be available, but it is not recommended for new designs. Contact us for current availability and alternate recommendations.
Commercial availability, condition, packaging and traceability are confirmed against your exact requirement through RFQ.
