4N26 Optocouplers – Phototransistor Output DIP-6

Description:

A Photocoupler is the most common and preferred choice for providing isolated feedback in a regulation loop. The 4N26 family is an industry-standard single-channel phototransistor coupler. Each optocoupler consists of a gallium arsenide infrared LED and a silicon NPN phototransistor.
