MOC3043XSM Description

Short technical summary and product information.

The MOC3043XSM from Isocom Components is an optically coupled isolator designed for driving power triacs. It consists of a Gallium Arsenide infrared emitting diode coupled with a monolithic silicon detector that performs the functions of a zero crossing bilateral triac.

 

This device offers a high isolation voltage of 5300Vrms and a peak blocking voltage of 400V. It features a zero voltage crossing circuit, making it suitable for applications where switching transients need to be minimized. The output is a Triac, and it requires a gate trigger current of 5mA.

 

The MOC3043XSM is supplied in a 6-SMD, Gull Wing package, designed for surface mounting. Its operating temperature range is -40°C to 100°C. This component is recognized by UL and approved by VDE.

 

Applications include power triac drivers, motor control, and consumer appliances where isolation between control and load circuits is critical.
