It comes in a 4-SOP (4.40 mm width) surface-mount package, making it a compact choice for breaking ground loops in industrial control, PLC digital inputs, and isolated power-supply feedback paths. ## CTR range sets the LED drive budget The current transfer ratio is specified between 40% and 80% at a forward current of 10 mA. ## Switching speed and timing margin Typical rise and fall times are 5.5 µs and 7 µs respectively, with turn-on and turn-off times of 9.5 µs and 8.5 µs. This is adequate for 10–100 kHz switching in isolated gate drives or status feedback loops, but not for high-speed data isolation — that calls for a digital isolator or a faster optocoupler family. ## Industrial temperature and supply voltage Rated for -40°C to 100°C operating temperature, the TCMT1101 fits outdoor telecom cabinets, motor drives, and factory-floor I/O modules without thermal derating. The output transistor can handle up to 70 V and 50 mA continuous.","metaTitle":"TCMT1101 Optoisolator, 3750Vrms, Transistor Output, 4-SOP","metaDescription":"TCMT1101 optocoupler with 3750Vrms isolation, transistor output, CTR 40-80% at 10mA.
