ISOCOM MOC3063XSM Optocoupler, Triac Output, 6-Pin, 600V

The ISOCOM MOC3063XSM is a 6-pin, zero-voltage crossing triac isolator designed for robust and reliable circuit protection and control. This surface-mount device integrates a gallium arsenide infrared emitting diode optically coupled with a monolithic silicon detector, effectively performing the functions of a zero-crossing bilateral triac. This sophisticated design ensures safe isolation and precise switching for a wide range of AC power control applications.

A core benefit of the zero-crossing operating mode is the significant reduction of electrical noise and electromagnetic interference (EMI) generated during switching. By activating the triac only when the AC voltage crosses zero, it minimises inrush currents and protects sensitive components downstream, leading to longer equipment life and improved system reliability. The device offers a high isolation voltage of 5.3 kV, providing a critical safety barrier between low-voltage control circuits and high-voltage mains power.

Key Applications

The MOC3063XSM is perfectly suited for power management systems, motor drive control circuits, and various consumer electronics. Its surface-mount DIP package makes it ideal for modern, automated PCB assembly, saving valuable board space while delivering high-performance isolation.
