The zero-crossing circuit fires the internal triac near the AC voltage zero, which limits the inrush current when switching resistive or lightly inductive loads like solenoids, heaters, or lamp banks. ## 600 V/µs dV/dt immunity for noisy line environments A minimum static dV/dt of 600 V/µs means the output triac will not falsely trigger from line transients or commutating noise on the AC mains. This matters when the opto drives a triac or SCR gate in a motor controller or industrial heater — the high dV/dt immunity keeps the load off until the LED side commands it. The LED trigger current is 5 mA max, with a typical forward voltage of 1.3 V. The hold current is 500 µA typical, so the output stays latched through the AC half-cycle once fired. The device is approved under IEC/EN/DIN and UL standards, which covers the safety barrier certification for most commercial and light-industrial equipment.","metaTitle":"onsemi MOC3083SVM Optoisolator, Triac Output, 800 V","metaDescription":"onsemi MOC3083SVM optoisolator with triac output, 800 V off-state, 4170 Vrms isolation, zero-crossing circuit.

Typical applications include solid-state relays, AC motor starters, lamp drivers, and solenoid valves where the control side (microcontroller or logic) must be isolated from the mains side."},{"question":"Will the MOC3083SVM drop into a board designed for the MOC3011SM?","answer":"Both parts share the same 6-SMD gull-wing package and 4170 Vrms isolation, but the MOC3083SVM includes a zero-crossing circuit while the MOC3011SM does not. The pinout is the same, so a board laid out for the MOC3011SM will accept the MOC3083SVM electrically and mechanically. The zero-crossing behaviour changes the turn-on timing — the MOC3083SVM only fires near the AC zero crossing, which eliminates inrush but adds a half-cycle delay versus the non-zero-cross part."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/MOC3083SVM","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/MOC3083SVM when reusing this data.
