MOC8101 – Transistor Output Optocoupler IC (DIP-6)

Description

The MOC8101 is a member of a high-reliability optocoupler family designed for secure, noise-free signal transmission between two electrically separated circuits. It features a gallium arsenide (GaAs) infrared-emitting diode that is optically coupled to a silicon planar phototransistor detector, all housed within a compact, industry-standard 6-pin dual-in-line package (DIP-6).

This device provides a robust isolation barrier, ensuring that sensitive low-voltage control circuitry is protected from high-voltage transients or electrical noise present in power stages. By omitting the base terminal, the MOC8101 offers improved common-mode interface immunity, making it an excellent choice for applications requiring stable performance in electrically noisy environments.
