Optoisolators, also known as optocouplers, are used for isolating an electrical signal from a microcontroller or other circuitry and controlling electric and electronic devices. They are commonly used for noise reduction, isolating signals from ground loops and providing communications between integrated circuits that must be kept isolated. SFH615AGR-X007T, belonging to the Transistor, Photovoltaic Output optoirsolator family, is a six-pin optoisolator with a high-efficiency infrared emitter LD and a fast and high-sensitivity phototransistor in one package.

SFH615AGR-X007T’s application field is in a broad range. It is used in automotive applications as in-car networking to transfer data between different ECU (electronic control units), isolated amplifier circuits, input/output control systems, telecommunication networking, industrial control systems, motor drive circuits and batteries management.

The working principle of SFH615AGR-X007T is based on the optocoupling effect, an effect that allows the electrical and the optical isolation. A light-emitting diode is on one side of the chip and a sensor on the other. The base of the light-emitting diode is connected to the input, i.e to the external voltage. Then, when an external voltage is applied to the chip, a light pulse is emitted which is detected by the sensor, which in turn creates an output.

The parasitic capacitance of SFH615AGR-X007T is close to zero, which proves the chip’s immunity from high-frequency noise and ground loops. Furthermore, the chip has a high stability across temperature ranges and offers a long service life with a minimum of optical power dissipation, which makes it one of the most reliable optoisolators on the market.

At the same time, SFH615AGR-X007T offers a low cost and a high isolation voltage between input and output of up to 5kV, which gives it the capability to control a wide range of devices. Furthermore, its fast switching speed makes it suitable for high-frequency applications.

The SFH615AGR-X007T optoisolator has been designed to provide a cost effective solution for various applications. It offers a high isolation voltage, a low cost, efficient power dissipation, and a long service life, which allows it to be used in many applications ranging from automotive, telecommunication, industrial control, and motor drive to battery management.
