4N35 - Phototransistor Optocoupler

General Description

The 4N35 is an optocoupler for general purpose applications.

It contains a light emitting diode optically coupled to a photo-transistor.

It is packaged in a 6-pin DIP package and available in wide-lead spacing option and lead bend SMD option.

Key Features
