| 4N35/ 4N36/ 4N37 Vishay Telefunken Optocoupler with Phototransistor Output Description The 4N35/ 4N36/ 4N37 consist of a phototransistor optically coupled to a gallium arsenide infraredemitting diode in a 6-lead plastic dual inline package. The elements are mounted on one leadframe using a coplanar technique, providing a fixed distance between input and output for highest safety requirements.
