The Darlington output with a separate base pin gives you the option to tailor the switching threshold or add external feedback — useful when you need to adjust the turn-off time or compensate for LED ageing. With a minimum current transfer ratio of 300% at 10mA forward current, the output can sink up to 150mA continuously. That CTR floor means the photodarlington will always deliver at least three times the input current to the load, so a 10mA LED drive gives you at least 30mA of collector current — plenty to drive a relay coil, a logic input, or a small solenoid directly. ## Package and mounting — 6-SMD gull wing The TIL113SM comes in a 6-pin surface-mount package with gull-wing leads (6-SMD). The 1.27mm lead pitch is standard for this class of optocoupler and routes easily on a two-layer board. The base pin (pin 6) is brought out — if you do not need it, leave it floating; the Darlington still switches normally. The operating temperature range of -40°C to 100°C covers industrial and outdoor equipment — motor drives, solar inverters, and HVAC controllers all fit within this envelope. ## Sourcing and lifecycle — active, no end-of-life signal The TIL113SM is listed as Active by onsemi with ROHS3 compliance.","metaTitle":"TIL113SM Optoisolator – onsemi, 4170Vrms, Darlington Output","metaDescription":"onsemi TIL113SM optoisolator: 4170Vrms isolation, Darlington with base output, 300% min CTR, 150mA output, -40°C to 100°C.
