MOC3043 Description

Short technical summary and product information.

The MOC3043 from Motorola is an optically isolated triac driver device. It integrates a GaAs infrared emitting diode with a light-activated silicon bilateral switch that functions like a triac. This optocoupler is designed for interfacing electronic controls with power triacs to manage resistive and inductive loads for 115 VAC operations.

 

Key electrical specifications include a typical LED forward voltage of 1.15V at 15mA and a maximum TRIAC output terminal voltage of 400V. It can handle a peak output current of 1A. The device offers zero-crossing capability, ensuring that the TRIAC begins conduction only when the AC wave reaches 0V, which helps avoid direct peak voltage.

 

The MOC3043 is suitable for applications requiring the control of AC loads up to 400V. Its zero-crossing feature is beneficial for preventing inrush current and reducing electromagnetic interference. The optocoupler is available in a 6-pin PDIP package, suitable for through-hole mounting.

 

This component provides protection for circuits handling high resistive and inductive loads. Its design allows it to operate effectively even at high temperatures, contributing to increased optocoupler lifespan.
