The Vishay 4N33 is an optically coupled isolator designed for high isolation between driving and load circuits. It utilizes a gallium arsenide infrared LED paired with a silicon photodarlington sensor.
Key features include a very high current transfer ratio of 500% minimum and high isolation resistance of 10^11 Ω typical. The device is housed in a standard plastic DIP-6 package, suitable for through-hole mounting.
These optocouplers are designed to replace reed and mercury relays, offering advantages such as long life, high-speed switching, and elimination of magnetic fields. They are suitable for applications requiring robust electrical isolation.
Agency approvals include UL 1577, cUL, DIN EN 60747-5-5 (VDE 0884-5), and FIMKO, indicating suitability for various industrial and safety-critical applications.
