The 10 kV/µs minimum static dV/dt rating means the output triac will not false-fire on fast-rising transients from inductive loads like motors, contactors, or solenoids. Operating temperature spans -55°C to 100°C, covering industrial cabinets and outdoor enclosures without needing a wider-grade part. ## Drive current and on-state limits On-state RMS current is rated at 300 mA, which covers small AC loads such as relays, pilot lamps, or solid-state relay input stages, but not high-power contactors directly. Hold current is 500 µA; below that the triac will commutate off at zero-cross, which is expected for a non-zero-crossing device (no zero-cross circuit is present). ## Package and production status Approvals include CQC, CSA, cUR, and UR — relevant for equipment destined for North American or Chinese markets where agency marks are required.","metaTitle":"IL4208-X009 Vishay Triac Optoisolator – 5300 Vrms","metaDescription":"Vishay IL4208-X009 single-channel triac optoisolator in 6-SMD tube. 5300 Vrms isolation, 800 V off-state, 10 kV/µs dV/dt.
