CNY17-1S-TA1

Optoisolators are devices that use light to electrically isolate two circuits. They are useful for protecting low power signal circuits from high power circuits. The CNY17-1S-TA1 is an optoisolator composed of a single transistor photovoltaic output. It is used to provide isolation between circuits, optically couple digital and analog signals, and provide protection against electrical disturbances.

The CNY17-1S-TA1 application field includes digital audio and video devices, signal and control boards, communication systems and optical line modules. It also serves to protect against overvoltage, power surges, and noise interference. The working principle of the CNY17-1S-TA1 is based on the photoelectric effect which is the emission of electrons from a material exposed to electromagnetic radiation. Specifically, a light emitting diode (LED) transmits light which is absorbed the photoconductor on the other side of the isolator.

When the LED is illuminated with current, a voltage is generated across the photoconductor. This voltage is then amplified by the transistor and output from the collector. The CNY17-1S-TA1 has an operating voltage range of 2V to 24V and a low output saturation voltage of 250mV. It can also achieve up to 4A of input current. The overshoot suppression circuit provides up to 300V overload protection for the optoisolator.

The CNY17-1S-TA1 is a reliable and economical device for providing electrical isolation in a wide variety of applications. It is highly efficient, with a working efficiency of up to 50%. It is also small in size, with a footprint of just 4.7mm x 4.7mm. Its low power consumption makes it suitable for use in portable devices, and its high speed response time of 50ns is ideal for fast signal transmission.

The CNY17-1S-TA1 optoisolator offers protection against noise, surges, and overvoltage while providing a safe electrical isolation between circuits. By using light to electrically isolate two circuits, it effectively blocks noise and interference from one circuit while preventing the circuits from interfering with each other. These features make it ideal for use in a wide range of digital audio and video devices, communication systems, signal and control boards, and optical line modules.
