Product details

Triac opto for direct mains switching

The MOC3023VM is a 1-channel triac-output optoisolator from onsemi, rated for 4170Vrms isolation and 400 V off-state voltage. The non-zero-crossing output means it triggers immediately on the LED pulse — no delay waiting for the AC zero — which makes it a fit for phase-control dimmers, solid-state relays, and soft-start circuits where you need to fire the triac at any point in the cycle.

Trigger current and drive margin

Forward voltage is 1.15V typ, and the LED can handle up to 60 mA continuous, giving plenty of headroom for derating over temperature. The hold current is 100 µA typ, which keeps the triac latched once fired on a low-current load.

Housed in a 6-DIP through-hole package with 0.300-inch pin spacing, the MOC3023VM is breadboard- and perfboard-friendly — easy to hand-solder and probe. Supplied in tube.

onsemi MOC3023VM is an active, RoHS3-compliant part. No stock-holding claim; availability confirmed at quote time.

Frequently asked questions

What is the pinout of MOC3023VM?

Design engineers need to verify PCB layout and ensure correct drive connections for the triac.

What is the isolation voltage of MOC3023VM?

Engineers must confirm creepage and safety compliance in isolated power designs.

Where can I buy MOC3023VM?

Buyers need to source the part quickly from authorized distributors to avoid counterfeit risk.

What is the price of MOC3023VM in tube quantity?

Sourcing buyers require current pricing to fill BOM lines within budget.

Is MOC3023VM obsolete or being EOL'd?

Maintenance and procurement need lifecycle status to plan for long-term availability and alternatives.

What are the alternatives to MOC3023VM?

Engineers and buyers look for drop-in replacements when parts are out of stock or need cost reduction.
