Its 800 V off-state voltage rating comfortably handles 240 VAC and 277 VAC mains lines with margin for line transients, while the 5300 Vrms isolation barrier provides reinforced insulation between the low-voltage control side and the mains-connected load side — a key safety parameter for designs needing CQC, cUL, UL, or VDE approval. The 100 mA RMS on-state current is suited for driving small AC loads directly; for higher-current loads, the phototriac typically gates an external power triac or SSR. A minimum static dV/dt of 1 kV/µs ensures the triac does not falsely trigger on fast-rising mains transients or switching noise — important in industrial environments with motor drives or contactors on the same line. The 4-SMD gull-wing package (supplier device package 4-SMD) is hand-solderable with a fine-tip iron — the gull-wing leads are visible for inspection and rework. The 0.05″ (1.27 mm) lead pitch is standard for optocouplers in this class. Available in Tape & Reel (TR) for automated pick-and-place or Cut Tape (CT) for prototyping and small runs — the CT option is handy for a weekend build or a first-article board. ## Active production and compliance It is ROHS3 compliant, and carries safety approvals from CQC, cUL, UL, and VDE, covering the major global markets for mains-isolated control. The operating temperature range of -55°C to 110°C covers industrial enclosures and outdoor telecom cabinets, though the 110°C upper limit is below automotive under-hood requirements.","metaTitle":"Vishay VOT8024AB-VT3 Phototriac, 800V, 5300Vrms, Zero-Cross","metaDescription":"Vishay VOT8024AB-VT3 phototriac, 800V off-state, 5300Vrms isolation, zero-crossing, active production, ROHS3.
