Product details

4170Vrms isolation and 600V off-state for line-voltage switching

The MOC3162SM is a 1-channel triac-output optoisolator from onsemi, built to drive a 600 V off-state load across a reinforced insulation barrier rated at 4170 Vrms. A zero-crossing circuit on the output triac fires near the AC voltage zero crossing, which limits inrush current and radiated EMI when switching resistive loads like heaters or incandescent lamps.

1kV/µs dV/dt immunity and LED trigger threshold

Static dV/dt is a minimum of 1 kV/µs, which means the output triac will not falsely trigger on fast line transients or commutating inductive loads. Forward voltage (Vf) is 1.3 V typical at If=10 mA, and the LED can handle up to 60 mA DC continuous. The hold current (Ih) is 500 µA typical, which keeps the triac latched once triggered until the load current drops below that threshold near the AC zero crossing.

Frequently asked questions

What package and mounting type does MOC3162SM use?

It comes in a 6-SMD gull-wing package for surface-mount assembly, supplied in tube format. The supplier device package is 6-SMD.

Can I replace MOC3162SM with MOC3063?

Both are zero-crossing triac optoisolators from onsemi, but the MOC3063 has a lower isolation voltage (4170 Vrms vs 4170 Vrms — same) and a different dV/dt rating. The MOC3063 typically offers 600 V off-state and similar trigger current, but pinout and package may differ. Confirm the exact specifications against your BOM before substituting.

How can I order MOC3162SM or check current availability?
