Product details

Triac output for AC load switching

The output blocks 400 V off-state, so it handles 240 VAC line switching with margin for transients. Because it has no zero-crossing circuit (non-zero-crossing), the triac fires immediately when the LED current exceeds the 5 mA trigger threshold. This makes it suitable for phase-control dimming, random-turn-on loads, or applications where the switch-on point must be independent of the AC line phase.

The 1.15 V typical forward voltage and 60 mA maximum DC forward current align with standard 5 V or 3.3 V logic drive; the 100 µA typical holding current keeps the triac latched once triggered until the load current drops below that level.

The part ships in tube and is available for RFQ against BOM quantities. The base product number MOC302 covers a family of triac optoisolators with different trigger currents and zero-crossing options.

Frequently asked questions

Is MOC3023SVM obsolete or still active?

It is still active — no end-of-life notice from onsemi. No last-time-buy pressure exists for this part.

What is the difference between MOC3023SVM and MOC3023?

The MOC3023 base number shares the same triac output and 400 V off-state rating. The SVM suffix indicates the 6-SMD gull wing surface-mount package and tube packaging, whereas the MOC3023 without suffix typically comes in a through-hole DIP package. Confirm the package variant before substituting.

Can MOC3023SVM be replaced with MOC3023M or other triac optocouplers?

The MOC3023M is a surface-mount variant with the same base die — check the package footprint (6-SMD gull wing vs. other SMD options) and trigger current (5 mA max,). For other triac optocouplers, verify off-state voltage (400 V,), isolation rating (4170Vrms,), and zero-crossing requirement (this part is non-zero-crossing,). A direct drop-in requires matching all four parameters.

What is the lead time for MOC3023SVM?

Lead time is confirmed at quote time based on current factory backlog and our inventory position. Because the part is active and widely used, typical lead times are manageable — submit an RFQ for your specific quantity and required delivery window.
