Optoisolators - Transistor, Photovoltaic Output

Optoisolators are devices which use light as a means of isolating two electronics circuits. This isolation is a necessary feature to suppress high voltage transients, protect high voltages, reduce ground loops and provide logic interface capability. A wide variety of optoisolators are available, each with its own application field. The CNY17F-3X017T Optoisolator belongs to the Transistor, Photovoltaic Output family, with a particular use in low-power general purpose applications.

The CNY17F-3X017T phototransistor optoisolator is an optically coupled device consisting of a gallium arsenide infrared emitting diode and a silicon NPN phototransistor. An optically isolated input is connected to the LED anode and a TTL compatible output is available from the phototransistor collector. The CNY17F-3X017T operates at a maximum output current of 20 mA and a maximum load current of 4mA with a minimum input of 10 mA.

The CNY17F-3X017T is suitable for use in a wide range of low-power general purpose optoisolator applications. It is designed for applications which need to switch a moderate load of up to 4mA at 20V, such as logic interface, electromagnetic interference (EMI) suppression, and AC power relays. The CNY17F-3X017T optoisolator module also provides a high degree of electrical isolation, up to 1000 volts, making it an ideal choice for applications in hazardous environments or high-voltage electrical transmission systems.

The CNY17F-3X017T optoisolator works on the principle of photovoltaic effect, according to which light is converted into electrical energy when incident on a suitable material. In the CNY17F-3X017T optoisolator, the light source is the LED, which emits light when connected to an input voltage. This light falls on the phototransistor, which is made up of a semiconductor material. The photon energy from the LED is converted into electrical energy by the phototransistor, which is proportional to the intensity of the light. The electrical energy is then used to control the switching action of the optoisolator.

The CNY17F-3X017T features a low power consumption, low cost, and small size. It is available in a variety of package styles, including Through-Hole, SMD, and Axial packages, to meet the specific needs of the application. The CNY17F-3X017T has a fast response time, good temperature stability, and a wide input voltage range. It also has the ability to drive low-level logic signals up to 3.5 volts.

The CNY17F-3X017T optoisolator is a popular choice for general purpose optoisolator applications. Its low cost, low power consumption, small size, and good temperature stability make it an ideal choice for many designs. Furthermore, its high degree of electrical isolation provides a reliable and safe solution for applications in hazardous environments or highly sensitive areas.
