TCLT1009

The Vishay Dale TCLT1009 is an optocoupler featuring a phototransistor output, designed for reliable signal isolation in electronic circuits. It is housed in a compact 4-lead SOP package, suitable for surface mount applications.

Key electrical characteristics include a high isolation voltage of 5000Vrms, a forward current rating of 60 mA, and a maximum collector current of 50 mA. The device offers a wide operating temperature range from -55°C to 100°C. The current transfer ratio (CTR) ranges from a minimum of 200% at 5mA to a maximum of 400% at 5mA, providing flexibility in design.

With a low Vce saturation voltage of 0.3V and fast switching times, including turn-on times as low as 6µs and turn-off times of 5µs, the TCLT1009 is suitable for various applications requiring efficient signal coupling and isolation. The series also boasts a creepage distance greater than 8 mm, enhancing its safety and reliability in demanding environments.

This optocoupler is ideal for applications such as switch-mode power supplies, computer peripheral interfaces, and microprocessor system interfaces where robust electrical isolation is critical. Its SMD low-profile 4-lead package facilitates integration into modern PCB designs.
