Optoisolators are electronic devices which allow current to be isolated between two circuits while still allowing data and signals to be transferred. The CNY17F1SD is a particular device which falls under the ‘Optoisolators - Transistor, Photovoltaic Output’ category. This device offers AC, DC and pulse isolation, and features a wide input, low voltage operation, high common mode voltage immunity and a fast response time.

The components of the CNY17F1SD are constructed from UL94V-0 flammability rated materials. The device itself is embedded inside a 300-mil SO-6 package which contains a high voltage optical coupling isolator, an amplifier optocoupler and a dual photovoltaic output transistor array. The optocoupler and photovoltaic output transistor array are separated from each other with isolation technology.

The device’s maximum power dissipation is 700mW and its input and output are optically isolated over a distance of 4.0mm. Its operating temperature range is -40 to +120°C providing it with a dielectric strength of 4.0kV r.m.s. Electrical isolation is provided up to 250V RMS.

The CNY17F1SD’s input signal detection is triggered when the input current is above 1mA, and it has an input current range between 0V up to 24V (Vcc) with a maximum collector-emitter voltage of 4.7V. The total input capacitance is 20pF. The device has a frequency range of 0.1 to 100kHz when Vcc is 5V.

The CNY17F1SD’s output voltage is set at 2.5V, with a maximum forward voltage drop of 0.25V and a maximum collector current of 1mA. The device’s response time (rise time) is around 2.5µs, while its fall time is 5.7µs. It also has a delay time (Vin to Vout) of 1µs.

Finally, the CNY17F1SD’s power consumption is rated at 200mW for both the input and the output. It has a static power dissipation of 1.2W and a forward current transfer ratio (CTR) of 40 to 440%.

In conclusion, the CNY17F1SD is a highly effective optoisolator device which provides comprehensive data signal and electrical isolation between two circuits. The device’s properties - such as its wide input, low voltage operation, high common mode voltage immunity and fast response time - make it an ideal solution for a range of applications, including automotive, industrial automation, consumer electronics, medical and communication systems.
