4N35 Description

Short technical summary and product information.

The 4N35 is a phototransistor optocoupler designed for applications requiring high input-output isolation. It features a minimum current transfer ratio (CTR) of 100% at 10mA forward current and a high input-output isolation voltage of 3,550Vrms for the 4N35 series.

 

This optocoupler has a typical response time of 3μs, making it suitable for high-speed switching applications. It is available in a standard dual-in-line package (DIP-6) with through-hole mounting.

 

Key electrical characteristics include a maximum operating isolation voltage of 420V peak and a transient voltage rating of 6000V peak. Safety limit values are specified for both the diode and phototransistor sides to ensure safe operation.

 

Applications for the 4N35 include power supply regulators, digital logic inputs, and microprocessor inputs, providing reliable signal isolation between different circuits.
