The 4170Vrms isolation rating means this part provides reinforced galvanic isolation between the input LED and the output phototransistor pair, suitable for breaking ground loops and protecting low-voltage logic from high-side transients in industrial control interfaces. This gain margin means a 5 V logic signal driving the LED can switch a 24 V PLC input module or a small relay coil without an external buffer transistor. ## Switching speed and output drive limits Turn-on time is 5 µs typical, but turn-off stretches to 100 µs max — the Darlington's stored base charge takes that long to clear. This asymmetry sets the practical switching ceiling below 5 kHz; for higher-speed isolation (serial data, PWM gate drive), a phototransistor or logic-output optocoupler is a better fit. The output transistor is rated for 30 V maximum collector-emitter, and the LED forward voltage is 1.2 V typical at 10 mA with an absolute maximum forward current of 80 mA. The 6-DIP package with 0.300-inch row spacing is a standard through-hole footprint that mates with sockets or wave-solder processes.","metaTitle":"onsemi TIL113M Optoisolator, 4170Vrms, Darlington Output","metaDescription":"onsemi TIL113M optoisolator: 4170Vrms isolation, Darlington with base output, 300% min CTR at 10mA, 150mA output, through-hole 6-DIP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Package":"Tube","Input Type":"DC","Output Type":"Darlington with Base","Mounting Type":"Through Hole","Package / Case":"6-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Number of Channels":"1","Voltage - Isolation":"4170Vrms","Vce Saturation (Max)":"1.25V","Operating Temperature":"-40°C ~ 100°C","Voltage - Output (Max)":"30V","Supplier Device Package":"6-DIP","Current - Output / Channel":"150mA","Current Transfer Ratio (Min)":"300% @ 10mA","Voltage - Forward (Vf) (Typ)":"1.2V","Turn On / Turn Off Time (Typ)":"5µs, 100µs (Max)","Current - DC Forward (If) (Max)":"80 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.77","stockQuantity":25,"priceTiers":[{"qty":1,"price":"$0.81000","currency":"USD"},{"qty":10,"price":"$0.52900","currency":"USD"},{"qty":100,"price":"$0.34660","currency":"USD"},{"qty":1000,"price":"$0.27364","currency":"USD"},{"qty":2000,"price":"$0.25540","currency":"USD"},{"qty":5000,"price":"$0.24628","currency":"USD"},{"qty":10000,"price":"$0.24263","currency":"USD"},{"qty":25000,"price":"$0.23715","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3b7a0e595c13b969737948a1da9a0357.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Will TIL113M drop into a panel that was specified around 4N25SR2M without rewiring?","answer":"No — the TIL113M is a through-hole 6-DIP package, while the 4N25SR2M is a surface-mount part.
