Its LED trigger current (Ift) is 7 mA maximum, so a standard logic-level GPIO with a series resistor can drive it directly — no extra transistor stage needed. The SCR output handles 150 mA RMS continuous on-state current, suited for low-power AC loads like a triac gate driver, solenoid valve, or indicator lamp in industrial control panels. ## 600 V off-state and 2500 Vrms isolation — the safety barrier With a 600 V off-state voltage rating and 2500 Vrms isolation, this photothyristor is suited for mains-isolated solid-state relay designs. The UR approval supports UL recognition for end-product compliance. ## 10 µs turn-on — no zero-cross, so expect phase-angle firing The 10 µs turn-on time and the absence of a zero-cross circuit mean this part fires as soon as the LED current exceeds the 7 mA threshold, regardless of the AC line phase. That is intentional for phase-angle control applications — dimming, heating, or motor speed control — where you want to trigger at any point in the half-cycle. The minimum static dV/dt of 5 V/µs gives reasonable immunity against false turn-on from fast voltage transients on a noisy mains line.","metaTitle":"TLP548J(TP1,F) Photothyristor, SCR Output, 600 V Off-State","metaDescription":"TLP548J(TP1,F) photothyristor with SCR output, 600 V off-state, 2500 Vrms isolation, 10 µs turn-on, 7 mA trigger.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"SCR","Turn On Time":"10µs","Mounting Type":"Surface Mount","Package / Case":"6-SMD, Gull Wing","Approval Agency":"UR","lifecycle_stage":"eol_hot","Number of Channels":"1","Static dV/dt (Min)":"5V/µs","Current - Hold (Ih)":"1mA","Voltage - Isolation":"2500Vrms","Voltage - Off State":"600 V","Operating Temperature":"-25°C ~ 85°C","Zero Crossing Circuit":"No","Supplier Device Package":"6-SMD","Voltage - Forward (Vf) (Typ)":"1.15V","Current - DC Forward (If) (Max)":"50 mA","Current - LED Trigger (Ift) (Max)":"7mA","Current - On State (It (RMS)) (Max)":"150 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.98","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.98000","currency":"USD"},{"qty":10,"price":"$0.91600","currency":"USD"},{"qty":25,"price":"$0.81400","currency":"USD"},{"qty":50,"price":"$0.77340","currency":"USD"},{"qty":100,"price":"$0.73270","currency":"USD"},{"qty":250,"price":"$0.65124","currency":"USD"},{"qty":500,"price":"$0.61054","currency":"USD"},{"qty":1500,"price":"$0.56984","currency":"USD"},{"qty":3000,"price":"$0.55967","currency":"USD"},{"qty":7500,"price":"$0.54949","currency":"USD"},{"qty":10500,"price":"$0.54135","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f1c210837b2c76fcea9d4c2240515827.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the trigger current for TLP548J(TP1,F)?","answer":"The maximum LED trigger current (Ift) is 7 mA.
