The integrated zero-crossing circuit triggers the output only near the AC voltage zero, which cuts the inrush current into resistive loads like heaters and incandescent lamps. ## 600 V/µs dV/dt immunity for inductive loads A minimum static dV/dt of 600 V/µs means the output Triac will not falsely trigger from fast voltage transients — the kind you get when switching motors, solenoids, or contactors. ## 4170 Vrms isolation and industrial temperature range Rated for 4170 Vrms isolation between input LED and output Triac — this satisfies reinforced insulation requirements for mains-connected equipment per UL. ## 5 mA LED trigger sensitivity The maximum LED trigger current is 5 mA — a standard logic output can drive it directly through a current-limiting resistor. The typical forward voltage is 1.3 V, so the resistor calculation is straightforward. The 500 µA typical hold current ensures the Triac stays latched through the zero-crossing until the load current drops below that threshold.","metaTitle":"MOC3083SR2M onsemi Optoisolator Triac Output 800V 6-SMD","metaDescription":"MOC3083SR2M onsemi optoisolator with Triac output, 800 V off-state, 4170 Vrms isolation, zero-crossing, 600 V/µs dV/dt.
