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. The LED trigger current (Ift) is a maximum of 10 mA, so a standard 5 V or 3.3 V logic output with a series resistor can drive the input side without a separate buffer. 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. ## Active lifecycle and compliance Operating temperature range is -40°C to 85°C, covering industrial and commercial environments.","metaTitle":"MOC3162SM onsemi Optoisolator – 4170Vrms, Zero-Cross Triac","metaDescription":"MOC3162SM onsemi optoisolator with triac output, 4170Vrms isolation, 1kV/µs dV/dt, zero-crossing circuit.
