Optocoupler with Phototransistor Output

Description

The 4N25(G)V/ 4N35(G)V series consists of a photo-

transistor optically coupled to a gallium arsenide

infrared-emitting 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.

Applications

Circuits for safe protective separation against

electrical

shock
