Product Description
Vishay TCMT1109 DC Input Optocoupler is a high-quality semiconductor device designed for electrical isolation between different parts of electronic equipment. It features a 4-pin mini-flat surface mount package, making it suitable for compact circuit board layouts. The device consists of a gallium arsenide infrared LED optically coupled to a phototransistor output, providing fast switching with typical rise time of 3μs and fall time of 4.7μs.
This optocoupler supports a maximum forward voltage of 1.6V and can handle an input current up to 60mA, operating reliably between -40°C to 100°C ambient temperature. Its isolation voltage of 3.75kVrms ensures robust protection against high voltage transients, enabling safe operation in demanding industrial and communication applications.
The device features a current transfer ratio (CTR) ranging from 200% to 400%, grouped for consistent performance, with a low temperature coefficient to maintain stability in varying environments. Compliance with multiple international standards including UL1577, FIMKO, DIN EN, and cUL CSA further assures quality and reliability.
Common uses include programmable logic controllers, modems, answering machines, and other general purpose electronic circuits requiring electrical isolation. Vishay's TCMT series provides a reliable solution for effective signal transmission without electrical connection risks.
