Its 4170 Vrms isolation rating covers reinforced insulation requirements for mains-coupled circuits such as solid-state relays, motor starters, and HVAC contactors. The built-in zero-crossing circuit turns on the triac only when the AC line voltage is near zero, which keeps conducted and radiated EMI low enough to pass CISPR 22 without extra filtering on resistive loads. ## dV/dt immunity and trigger current prevent false turn-on A minimum static dV/dt of 1 kV/µs means the output triac will not falsely trigger from fast voltage transients on the mains, a common failure in inductive-load switching or noisy line conditions. Maximum LED trigger current (Ift) is 5 mA, which allows direct drive from a 3.3 V or 5 V GPIO through a current-limiting resistor. The typical hold current (Ih) of 500 µA ensures the triac stays latched once triggered until the load current drops below that threshold at the AC zero-cross. ## Active production with industrial temperature coverage Procurement can plan standard lead-time orders without obsolescence risk. The 6-SMD Gull Wing package supports standard reflow soldering and visual inspection. ROHS3 compliance and IEC/EN/DIN, UL approvals simplify compliance for export and safety-certified designs.","metaTitle":"MOC3163SR2VM onsemi Optoisolator Triac Output 6-SMD Gull","metaDescription":"MOC3163SR2VM onsemi optoisolator with triac output, 4170 Vrms isolation, 600 V off-state, zero-crossing, 1 kV/µs dV/dt.
