MPN:EL3021

The EL3021 is Everlight’s version of the popular MOC3021 optotriac driver IC, designed to provide safe and reliable AC load control. It uses an infrared LED input optically coupled to a triac output, ensuring strong electrical isolation between low-voltage control circuits and high-voltage AC lines.

Since it is a random-phase trigger optocoupler, the EL3021 is ideal for phase-control applications such as light dimmers, motor speed controllers, and solid-state relays where triggering must occur at any point in the AC cycle.

MPN:3041

The EL3041 is Everlight’s equivalent of the popular MOC3041 zero-cross optotriac driver IC, designed for safe and reliable AC load switching. It uses an infrared LED input optically coupled to a triac output, providing excellent electrical isolation between low-voltage control circuits and high-voltage AC lines.

With its zero-cross detection feature, the EL3041 turns on the load only when the AC waveform crosses zero voltage, significantly reducing electrical noise (EMI) and increasing triac and load life. This makes it ideal for on/off AC control applications where phase control is not required.
