CNY65Exi

Vishay Telefunken

Optocoupler with Phototransistor Output

Description

The CNY65Exi consists of a phototransistor optically
coupled to a gallium arsenide infrared-emitting diode
in a 4-lead plastic package.
The single components are mounted in opposite one­another, providing a distance between input and
output for highest safety requirements of > 3 mm.
