The 600 V off-state voltage rating covers 120 VAC and 240 VAC mains with healthy margin for line surges. A minimum static dV/dt of 1kV/µs on the output side ensures the triac does not falsely trigger from fast line transients or commutating noise — a common failure point in motor-drive and relay-coil circuits. ## Parametric deep-dive: trigger current, hold current, and temperature range The LED trigger current (Ift) is 5 mA maximum — low enough to be driven directly from a 3.3 V or 5 V GPIO through a series resistor, eliminating the need for a separate transistor driver. Once triggered, the triac latches on until the load current drops below the 300 µA typical hold current (Ih). The on-state RMS current rating is 70 mA maximum, suitable for low-power loads like solid-state relay inputs, indicator lamps, or small AC solenoids. The forward voltage drop across the LED is 1.2 V typical at rated forward current. Operating temperature spans -40°C to 100°C, placing it firmly in the industrial-grade bracket — usable in outdoor telecom cabinets, HVAC controls, and factory-floor I/O modules without derating concerns. ## Active production, ROHS3 compliant, surface-mount package The ROHS3 compliance mark confirms it meets current EU substance restrictions without exemption conflicts. Supplied in Tape & Reel (TR) and Cut Tape (CT) options, the 4-SMD Gull Wing package is a standard surface-mount footprint for reflow assembly. The cUR and UR agency approvals simplify global equipment certification paths. ## Design-in note: no zero-crossing circuit, plan edge triggering The FODM3053R2-NF098 does not include a zero-crossing detection circuit. The triac fires immediately when the LED current exceeds the trigger threshold, regardless of the AC line phase. This is typical for random-phase (phase-angle) control applications like resistive heater modulation or soft-start circuits. For zero-cross switching of inductive loads, select a sibling with integrated zero-cross circuitry.","metaTitle":"FODM3053R2-NF098 onsemi Triac Optoisolator 3750Vrms 600V SMD","metaDescription":"FODM3053R2-NF098 onsemi Triac output optoisolator, 3750Vrms isolation, 600V off-state, 1kV/µs dV/dt.
