ONSEMI 4N33SR2M High-Sensitivity Optocoupler
The 4N33SR2M is a high-sensitivity, six-pin DIP optocoupler designed for low-power logic circuits, telecommunications equipment, and solid-state relays. Featuring high electrical insulation ratings, including UL1577 and IEC standards, it ensures safe electrical isolation up to 850 V peak working voltage. Its photodarlington configuration is optically coupled with a gallium arsenide infrared emitter and a silicon photodarlington detector, providing reliable data transfer with low input drive current. Suitable for interfacing systems of different potentials, it offers excellent performance with an isolation voltage of 4170 VACrms and a typical CTR of 50-600%, operating over temperatures from -40°C to 100°C.
