Optoisolators are used in electronic circuits and systems as a signal- or power-level configurable isolator. The PC817X3NSZ0F is part of a line of optoisolators manufactured by Sharp. It is a transistor, photovoltaic output optoisolator that has a broad range of application fields.

PC817X3NSZ0F Features

The PC817X3NSZ0F features an open-drain/collector output, an isolation voltage of up to 2.5kV (at 1mA gate current), and a maximum power rating of 75mW. It also has a CTR (Current Transfer Ratio) value that ranges from 10% to 240% and a maximum collector-emitter saturation voltage of 1.5V. Furthermore, the PC817X3NSZ0F has a forward current transfer ratio of 10%, a peak collector current of 200mA, and an ambient temperature range of -55°C to +100°C.

Application Fields

The PC817X3NSZ0F optoisolator is ideal for various applications. It is used in industrial, automotive, consumer, medical, and building automation systems. In particular, it is used in PLCs (Programmable Logic Controllers), communication networks, or fieldbus systems. It can also be used in lighting and motor control systems, as well as in AC and DC voltages, in order to insulate, protect, and detect signals or power.

Working Principle

The PC817X3NSZ0F optoisolator functions by transferring a current or voltage from one side to the other via a photovoltaic input stage. This is accomplished by a combination of two isolated provinces that are separated by a laser diode or a light-emitting diode. Light from the LED is detected by a photodiode, which is then converted to an electric current at the output. This electric current is then used to actuate an electrical switch or to send an electrical signal.

Conclusion

The PC817X3NSZ0F optoisolator can be used in various application fields. It has an open-drain/collector output, an isolation voltage of up to 2.5kV, and a maximum power rating of 75mW. Furthermore, it has a CTR value that ranges from 10% to 240%, and a maximum collector-emitter saturation voltage of 1.5V. Its working principle involves a photovoltaic input stage using an LED and a photodiode.
