This combination suits it for driving low-current AC loads — solenoids, small valves, or triac gate triggers — where the control side must be galvanically separated from the line-voltage side. The 1 kV/µs minimum static dV/dt means the output Triac resists false turn-on from fast-rising mains transients or inductive-load switching edges. In a motor-drive or relay-coil switching circuit, that immunity prevents the optocoupler from self-triggering when the AC line commutates. ## Random-phase trigger — no zero-cross, full phase-angle control With no zero-crossing circuit, the VOT8123AD-V fires the Triac at whatever point in the AC cycle the LED current is applied. This makes it usable for phase-angle dimming or proportional heating control, not just on/off switching at the zero crossing. The LED trigger current is 10 mA max, and the forward voltage is 1.2 V typical — the MCU or logic output driving it must source that current through a series resistor. The hold current is 400 µA typical, so the load must draw at least that much to keep the Triac latched once triggered. On-state RMS current is 100 mA maximum — this is a signal-level or low-current driver, not a power-switching Triac. Its job is to drive the gate of an external power Triac or a small AC load directly. ## Industrial temperature range and global approvals The VOT8123AD-V operates from -40°C to +110°C, covering the industrial temperature band for factory-floor control cabinets, HVAC panels, and outdoor telecom power supplies. It carries approvals from CQC (China), cUL and UL (US/Canada), and VDE (Germany), so it meets the regulatory requirements for equipment sold into North American, European, and Chinese markets without additional component-level certification. ## Through-hole 6-DIP — board-fit and assembly The supplier device package is 6-DIP, and the part ships in Tube format.","metaTitle":"Vishay VOT8123AD-V Optotriac, 800V Off-State, 5000Vrms","metaDescription":"Vishay VOT8123AD-V phototriac optocoupler: 800V off-state, 5000Vrms isolation, 1kV/µs dV/dt, no zero-cross, 6-DIP through-hole.
