Triac output with zero-crossing — what it means for the load
The MOC3082SM: The triac output switches AC loads up to 800 V off-state, and the built-in zero-crossing circuit triggers the triac only near the AC voltage zero point. This reduces inrush current and EMI when switching inductive loads like solenoids, relays, or small motors — the triac sees a soft turn-on instead of a hard slam. With a minimum static dV/dt of 600 V/µs, the output resists false triggering from line transients or commutation noise — a common failure mode in noisy industrial environments where a standard optotriac would self-fire and latch on.
6-SMD Gull Wing — rework and board-fit
Housed in a 6-SMD Gull Wing package (supplier device package 6-SMD), this part is surface-mount and reworkable with standard hot-air tools. The gull-wing leads are visible for inspection and touch-up — no hidden joints under the body. The tube packaging suits pick-and-place lines that feed from tube magazines; the part is not supplied in tape-and-reel, so factor that into your assembly feeder setup.
Isolation and regulatory acceptance
Rated for 4170Vrms isolation between input and output, the MOC3082SM meets the creepage and clearance requirements for reinforced insulation in mains-connected equipment. UL recognized and ROHS3 compliant — it carries the approvals needed for most commercial and industrial power supplies, motor drives, and HVAC controls.
