The TCMT110. series is a single-channel optocoupler with a phototransistor output, designed for signal isolation in applications such as programmable logic controllers and modems. It is housed in a 4-pin SSOP-4 package measuring 7.00 mm in length with a half-pitch design. The device provides 3750 V RMS isolation voltage, low coupling capacitance of 0.3 pF, and operates over an ambient temperature range of -40 to +100 °C. It meets UL1577, cUL, VDE, and CQC safety standards with double protection. The TCMT1109 variant supports a current transfer ratio (CTR) of 200 to 400% at 5 mA forward current and 5 V collector-emitter voltage. The package has a creepage and clearance distance of at least 5 mm and insulation thickness of 0.4 mm. Soldering is compliant with J-STD-020, and the device is rated for a junction temperature up to 125 °C.
