The part is listed as Active, so it remains a current BOM line without an imminent end-of-life watch. ## Isolation, off-state voltage, and dV/dt immunity Rated for 4170 Vrms isolation between the LED input and the triac output, this part suits applications requiring reinforced insulation per UL. The off-state voltage is 600 V, which covers 240 VAC mains with margin. Static dV/dt immunity is a minimum of 1 kV/µs — this prevents the triac from falsely triggering on fast voltage transients from motor contactors or relay switching. ## Package, temperature range, and drive current Housed in a 6-DIP through-hole package with a 0.300-inch (7.62 mm) body width, the MOC3163M operates over -40°C to 85°C, covering most industrial and appliance environments. The LED forward voltage is 1.3 V typical, and the maximum LED trigger current is 5 mA — compatible with 3.3 V or 5 V logic outputs through a current-limiting resistor. Hold current is 500 µA typical, so the triac latches once triggered and turns off at the load current zero crossing.","metaTitle":"MOC3163M onsemi Optoisolator, Triac Output, 4170 Vrms","metaDescription":"onsemi MOC3163M optoisolator with triac output, 4170 Vrms isolation, zero-crossing circuit, 600 V off-state, 1 kV/µs dV/dt.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Package":"Tube","Output Type":"Triac","Mounting Type":"Through Hole","Package / Case":"6-DIP (0.300\\\", 7.62mm)","Approval Agency":"UL","lifecycle_stage":"eol_hot","Number of Channels":"1","Static dV/dt (Min)":"1kV/µs","Current - Hold (Ih)":"500µA (Typ)","Voltage - Isolation":"4170Vrms","Voltage - Off State":"600 V","Operating Temperature":"-40°C ~ 85°C","Zero Crossing Circuit":"Yes","Supplier Device Package":"6-DIP","Voltage - Forward (Vf) (Typ)":"1.3V","Current - DC Forward (If) (Max)":"60 mA","Current - LED Trigger (Ift) (Max)":"5mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.83","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.83000","currency":"USD"},{"qty":10,"price":"$1.15700","currency":"USD"},{"qty":100,"price":"$0.85630","currency":"USD"},{"qty":500,"price":"$0.78690","currency":"USD"},{"qty":1000,"price":"$0.64804","currency":"USD"},{"qty":2000,"price":"$0.61564","currency":"USD"},{"qty":5000,"price":"$0.60175","currency":"USD"},{"qty":10000,"price":"$0.58786","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/bf2f6ab6d1f2280bfc0a67ba9bb40c29.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MOC3163M zero crossing?","answer":"Yes, the MOC3163M includes a zero-crossing circuit.
