It provides 4000 Vrms of isolation between the LED input and the SCR output, with a 600 V off-state voltage rating that suits it for switching AC loads up to 150 mA RMS on-state current. The 5 V/µs minimum static dV/dt immunity helps prevent false triggering in the presence of fast voltage transients common on mains-powered industrial equipment. ## Turn-on time and trigger sensitivity With a typical turn-on time of 15 µs and a maximum LED trigger current of 10 mA, this part is designed for direct drive from logic-level signals or microcontroller I/O pins. The 1.15 V typical forward voltage and 50 mA maximum DC forward current give a reasonable LED drive budget. Once triggered, the SCR latches on until the holding current of 1 mA is interrupted — no zero-crossing circuit is included, so the output turns on immediately regardless of the AC line phase. ## Industrial temperature range and approvals Safety approvals from BSI, SEMKO, UR, and VDE cover the 4000 Vrms isolation rating, simplifying compliance for equipment sold into European and North American markets.","metaTitle":"TLP748J(D4,F) SCR Optoisolator, 600 V Off-State, 4000 Vrms","metaDescription":"Toshiba TLP748J(D4,F) single-channel SCR optoisolator in 6-DIP through-hole package. 600 V off-state, 4000 Vrms isolation, 5 V/µs dV/dt immunity.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Package":"Tube","Output Type":"SCR","Turn On Time":"15µs","Mounting Type":"Through Hole","Package / Case":"6-DIP (0.300\\\", 7.62mm)","Approval Agency":"BSI, SEMKO, UR, VDE","lifecycle_stage":"eol_hot","Number of Channels":"1","Static dV/dt (Min)":"5V/µs","Current - Hold (Ih)":"1mA","Voltage - Isolation":"4000Vrms","Voltage - Off State":"600 V","Operating Temperature":"-40°C ~ 100°C","Zero Crossing Circuit":"No","Supplier Device Package":"6-DIP","Voltage - Forward (Vf) (Typ)":"1.15V","Current - DC Forward (If) (Max)":"50 mA","Current - LED Trigger (Ift) (Max)":"10mA","Current - On State (It (RMS)) (Max)":"150 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.82","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.82000","currency":"USD"},{"qty":10,"price":"$1.15400","currency":"USD"},{"qty":100,"price":"$0.85390","currency":"USD"},{"qty":500,"price":"$0.78466","currency":"USD"},{"qty":1000,"price":"$0.64620","currency":"USD"},{"qty":2000,"price":"$0.61389","currency":"USD"},{"qty":5000,"price":"$0.60004","currency":"USD"},{"qty":10000,"price":"$0.58619","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d82e88890b122ccee325f525b86b43e9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is TLP748J(D4,F) obsolete or end-of-life?","answer":"No."},{"question":"What is the closest functional second-source for TLP748J(D4,F)?","answer":"The TLP748J(F) is a functionally similar SCR-output optoisolator sharing the same 5 V/µs static dV/dt, 15 µs turn-on time, single-channel through-hole design, and agency approvals (BSI, SEMKO, UR).
