It combines a GaAs infrared LED with a zero-crossing triac detector, rated for 600 V off-state voltage and 3750 Vrms isolation. The zero-crossing circuit means the triac only turns on near the AC zero-voltage point, which dramatically reduces inrush current and radiated EMI when switching resistive or lightly inductive loads like heaters, solenoid valves, or incandescent lamps. ## 3750 Vrms isolation and industrial temperature range The 3750 Vrms isolation voltage qualifies the TLP268J(E for reinforced insulation in mains-connected equipment per IEC 60950-1 and IEC 62368-1, making it suitable for power supplies, motor drives, and industrial controllers where the low-voltage control side must be safely separated from the AC line. The 600 V off-state rating provides ample margin for 240 VAC or 277 VAC line switching, and the typical static dV/dt of 500 V/µs ensures the triac does not falsely trigger on fast mains transients — a common failure point in cheaper couplers. ## Package and approvals — a standard footprint with global safety marks The TLP268J(E comes in a 6-SOIC (0.173\", 4.40 mm width) 4-lead package, which is a standard photocoupler footprint shared by many Toshiba and competitor parts — easy to hand-solder or reflow, and straightforward to second-source if needed. It carries CQC, cUR, and UR safety approvals, covering North American and Chinese regulatory requirements for AC-line isolation components. The forward voltage is typically 1.27 V, and the maximum DC forward current is 30 mA, with a typical hold current of 200 µA — the minimum current needed to keep the triac latched after the LED turns off. ## Lifecycle and sourcing If you need a dual-source option for supply resilience, Toshiba offers several pin-compatible triac couplers in the same 6-SOIC 4-lead package — the TLP268J(E) is the low-trigger-current variant (3 mA max Ift), so a direct replacement would need to match that threshold.","metaTitle":"TLP268J(E Triac Coupler, 600 V Off-State, 3750 Vrms","metaDescription":"TLP268J(E triac output photocoupler from Toshiba. 600 V off-state, 3750 Vrms isolation, zero-crossing, 100 µs turn-on, -40°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":"100µs","Mounting Type":"Surface Mount","Package / Case":"6-SOIC (0.173\\\", 4.40mm Width), 4 Leads","Approval Agency":"CQC, cUR, UR","lifecycle_stage":"eol_hot","Number of Channels":"1","Static dV/dt (Min)":"500V/µs (Typ)","Current - Hold (Ih)":"200µA (Typ)","Voltage - Isolation":"3750Vrms","Voltage - Off State":"600 V","Operating Temperature":"-40°C ~ 100°C","Zero Crossing Circuit":"Yes","Supplier Device Package":"6-SOP","Voltage - Forward (Vf) (Typ)":"1.27V","Current - DC Forward (If) (Max)":"30 mA","Current - LED Trigger (Ift) (Max)":"3mA","Current - On State (It (RMS)) (Max)":"70 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.99","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.99000","currency":"USD"},{"qty":10,"price":"$0.64400","currency":"USD"},{"qty":100,"price":"$0.42220","currency":"USD"},{"qty":1000,"price":"$0.33330","currency":"USD"},{"qty":2000,"price":"$0.31108","currency":"USD"},{"qty":5000,"price":"$0.29997","currency":"USD"},{"qty":10000,"price":"$0.29553","currency":"USD"},{"qty":25000,"price":"$0.28886","currency":"USD"}]},"links":{"datasheetUrl":"https://toshiba.semicon-storage.com/info/TLP268J_datasheet_en_20200217.pdf?did=14464&prodName=TLP268J","sourceUrl":null},"ai":{"faq":[{"question":"Does TLP268J(E have a zero-crossing feature?","answer":"Yes, the TLP268J(E includes a zero-crossing circuit.
