It switches AC loads like solenoids, relays, or small motors from a low-voltage control side without a galvanic path back to the microcontroller. ## No zero-crossing — phase-angle control ready This part has no zero-crossing circuit, so the Triac fires as soon as the LED current exceeds the 10 mA trigger threshold. That makes it suitable for phase-angle dimming or soft-start applications where you need to switch on at any point in the AC cycle, not just the zero-cross. The minimum static dV/dt is 1 kV/µs, which means the output Triac won't falsely trigger from fast voltage transients on the AC line — a common failure mode in noisy industrial environments. Typical holding current is 220 µA, so once triggered, the Triac stays latched until the load current drops below that threshold near the AC zero-cross. ## Surface-mount 6-SMD Gull Wing for reflow assembly Packaged in a 6-SMD Gull Wing (6-SMD, Gull Wing) format, this optoisolator is designed for standard reflow soldering. The base product number is MOC305, indicating it belongs to the MOC305x family of random-phase Triac optoisolators from onsemi.","metaTitle":"onsemi MOC3052SR2M Optoisolator, Triac Output, 600 V, 6-SMD","metaDescription":"onsemi MOC3052SR2M optoisolator with Triac output, 600 V off-state, 4170 Vrms isolation, 1 kV/µs dV/dt, active production, RoHS3 compliant.

The MOC3073SVM has a lower trigger current (6 mA vs 10 mA) and ships in Tube packaging, while the MOC3052SR2M comes in Tape & Reel. The MOC3052SR2M's higher trigger current may require a stronger LED drive from the microcontroller but offers better noise margin in high-interference environments."},{"question":"What compliance documentation does onsemi provide for MOC3052SR2M?","answer":"onsemi provides UR approval and ROHS3 Compliance for the MOC3052SR2M.
