4N25-X009T Description

Short technical summary and product information.

The 4N25-X009T is an industry-standard single-channel optocoupler featuring a gallium arsenide infrared LED and a silicon NPN phototransistor. It provides a high isolation test voltage of 5000 VRMS, achieved through specialized manufacturing processes.

 

This optocoupler is designed for interfacing with common logic families and boasts a low input-output coupling capacitance of less than 0.5 pF. It is available in a standard dual-in-line 6-pin package suitable for through-hole mounting and is also offered in tape and reel configurations for surface mounting applications.

 

Key applications include AC mains detection, reed relay driving, switch mode power supply feedback, telephone ring detection, logic ground isolation, and logic coupling with high-frequency noise rejection. Agency approvals include UL, cUL, BSI, FIMKO, CQC, and VDE (with option 1).

 

Compliance includes RoHS Directive 2002/95/EC and WEEE 2002/96/EC.
