Optoisolators - Transistor, Photovoltaic Output

The CNY17F4SM is a 4-pin opto-isolator mounted in a 4-Pin SOP Package. It uses a photo transistor output and features a voltage rating of 5V, an isolation voltage of 3000V, and a lead pitch of 0.5mm. It has a low collector-emitter dark current of 5μA max, a short circuit current of 25mA and a switching speed of 2us max.

The CNY17F4SM is designed to provide electrical isolation between input and output circuits, thus preventing current flow and eliminating ground loops. It works by using a light emitting diode (LED) to send light of a certain wavelength to a photosensitive transistor mounted in a hermetically sealed package. The light is converted by the photosensitive components into electric current, which controls the transistor output.

The CNY17F4SM is a digital opto-isolator ideal for use in motor control, security systems, process automation, and industrial control applications. It is designed for direct mounting on printed circuit boards and is suitable for use in devices that require up to 5V of power. It can be used to isolate inputs from outputs, between applications on the same board, and between circuits on different boards. It can also be used to provide separation between high voltage and low voltage systems.

The CNY17F4SM is a useful device for protecting sensitive circuits from electrical overloads, transients, and other faults. It is widely used to isolate control and power circuits to provide safety for personnel and equipment. Because it is an opto-isolator, it does not generate electromagnetic interference to the devices connected to it, making it ideal for use in high-frequency applications.

In addition to providing electrical isolation, the CNY17F4SM offers a high insulation resistance and dielectric strength. It is designed to provide insulation of up to 3000Vrms, making it suitable for use in medical, industrial, and laboratory applications. It is also low cost, highly reliable, and long-lasting, making it an economical solution.

The CNY17F4SM opto-isolator is a device that is widely used in an array of applications to provide electrical isolation between input and output signals. By providing a high insulation resistance and dielectric strength, it is designed to protect sensitive circuits from electrical overloads, transients, and other faults. It is also designed to offer a low collector-emitter dark current and switching speeds of up to 2us max.
