Its 800 V off-state voltage lets it block standard 240 VAC mains with healthy margin, and the built-in zero-crossing circuit fires the triac near the voltage zero crossing, which limits inrush current and radiated EMI when driving resistive loads like heaters, incandescent lamps, or solenoid valves. ## 10 kV/µs dV/dt immunity — false-trigger protection in noisy environments A minimum static dV/dt of 10 kV/µs means the output triac won't falsely trigger from fast voltage transients on the AC line — a common problem in motor-drive cabinets, contactor panels, and industrial power supplies where inductive switching couples noise back onto the mains. This rating is what separates a part that stays off when it should from one that flickers the load. ## 300 mA on-state — direct-drive limit and external triac trigger The 300 mA RMS on-state current handles small loads directly — a 24 VAC pilot lamp, a solid-state relay input, or a PLC digital output. For higher-current loads (motors, contactors, large heaters) this part serves as the gate driver for an external power triac or SCR, with the 2 mA maximum LED trigger current keeping the microcontroller I/O pin happy. ## Package and mounting — 6-SMD for reflow assembly Housed in a 6-pin surface-mount package (6-SMD), this part is suited for automated reflow soldering. The Tube shipping medium is fine for prototype and low-volume builds; for production, check whether the reel option is available from the same distributor. The -55°C to 100°C operating range covers most industrial enclosures but stops short of automotive under-hood environments.","metaTitle":"IL4108-X017 Optoisolator, 5300 Vrms Triac Output","metaDescription":"IL4108-X017 optoisolator with triac output, 5300 Vrms isolation, 800 V off-state, 10 kV/µs dV/dt, zero-crossing, -55°C to 100°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Package":"Tube","Output Type":"Triac","Turn On Time":"35µs","Mounting Type":"Surface Mount","Package / Case":"6-SMD","Approval Agency":"CSA, UR, VDE","lifecycle_stage":"eol_hot","Number of Channels":"1","Static dV/dt (Min)":"10kV/µs","Current - Hold (Ih)":"500µA","Voltage - Isolation":"5300Vrms","Voltage - Off State":"800 V","Operating Temperature":"-55°C ~ 100°C","Zero Crossing Circuit":"Yes","Voltage - Forward (Vf) (Typ)":"1.16V","Current - DC Forward (If) (Max)":"60 mA","Current - LED Trigger (Ift) (Max)":"2mA","Current - On State (It (RMS)) (Max)":"300 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.95","priceTiers":[{"qty":1,"price":"$3.95000","currency":"USD"},{"qty":10,"price":"$2.79300","currency":"USD"},{"qty":100,"price":"$2.28790","currency":"USD"},{"qty":500,"price":"$1.92874","currency":"USD"},{"qty":1000,"price":"$1.76913","currency":"USD"},{"qty":2000,"price":"$1.69597","currency":"USD"},{"qty":5000,"price":"$1.66271","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3d733fc231feb010bf94b3e877d16d18.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IL4108-X017/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between IL4108-X017 and IL4108-X016?","answer":"The IL4108-X017 and IL4108-X016 are both single-channel optoisolators with triac output in a 6-SMD package, sharing the same 5300 Vrms isolation and 800 V off-state voltage.
