TLP2403(F) optoisolators offer a fundamental isolation of input and output by dissociation of the two circuits, providing reliable protection for electrical signals. It allows electrical signals to be exchanged without direct electric contact that may cause damage for each circuit. It can be effectively used for the protection of data or controls.

Typical applications include:

• Communication equipment (modems, digital devices, etc.)
• Computer peripheral equipment (printers, keyboards, etc.)
• Automation process machinery (machine tools, injection molding, etc.)
• Car audio systems
• Emergency lighting control systems
• Security systems

The TLP2403(F) optoisolator is designed to provide optimized protection against electrical noises and is suitable for high frequency applications. It utilizes a photo MOS device as an output, allowing low on state resistance and high output current of 120mA. The input is optical source of gallium arsenide infrared diode and the output circuit consists of a MOS transistor.

The optoisolator is designed to provide a high degree of isolation between the source and the sink. The LED provides electrical isolation by radiation and typically exceeds 10^7 Vrms maximum isolation. In addition, the optoisolator provides high immunity to withstand input transients and a high common mode transient immunity of over 10 kV/μs.

The TLP2403(F) optoisolator works by sensing the input signal from the photo diode and converting it into a current. The current is then used to activate the optically coupled MOS transistor output. The output signal is then rapid switched to the ON or OFF position by the control of the MOS transistor, depending upon the input signal.

The TLP2403(F) offers high-temperature stability with long service life, minimal crosstalk, excellent noise suppression capability and an optical response time of 10 μs. It also features a low trigger current of 15mA and a forward voltage of 2.5V. The device is highly reliable with a high isolation voltage of 740Vrms, making it suitable for a range of industrial equipment.

In conclusion, the TLP2403(F) optoisolator is a versatile device used in a variety of applications. It provides excellent electrical and optical isolation, high speed response time and long-term reliability. The optoisolator is ideal for noisy environments, protecting from electrical transients and providing optimal protection for data or control signals.
