The Vishay TCMT1109 is a single-channel optocoupler designed for applications requiring electrical isolation. It consists of an infrared-emitting diode coupled to a phototransistor, providing a high isolation voltage of 3750Vrms.
This optocoupler operates with a forward current of 60 mA and features a maximum collector current of 50 mA. The Vce saturation voltage is a maximum of 300mV at 5mA, and the typical forward voltage is 1.6V. The current transfer ratio (CTR) ranges from a minimum of 200% to a maximum of 400% at 5mA.
Designed for surface mounting, the TCMT1109 comes in a compact 4-SOP package with dimensions of 2.8mm length, 4.4mm width, and 1.9mm height. It operates within a wide ambient temperature range of -40°C to 100°C. The device is available on tape and reel.
Key applications include programmable logic controllers, modems, and answering machines, where reliable signal isolation is critical. Agency approvals include UL1577 and DIN EN 60747-5-5.
