The ACPL-847-000E optoisolator is a small, highly integrated device capable of providing electrical isolation between low voltage and high voltage circuits. It is specifically designed for applications requiring isolation of a logic control system from its power supply. The ACPL-847-000E optoisolator consists of a dual LED array coupled to a photo detector output transistor. Its key features include a low input current, a high operating temperature range, and a low minimum input–output offset voltage.The device can switch up to 100mA of load current and is available in surface mount and through-hole packages.

The ACPL-847-000E\'s spatial isolation technology, also known as photoelectric isolation, entails the use of a pair of optically coupled elements to separate two or more circuits electrically while permitting them to exchange data. This isolation eliminates potential electrical hazards and improves system reliability.

In the ACPL-847-000E optoisolator, the LED array, when energized, emits infrared light. This light is received by the silicon photo detector, which acts as a switch. The light causes electrons to flow through the photo detector, resulting in a current. This current is used to control the output transistor, which is connected between two low-voltage terminals.

The characteristics of the ACPL-847-000E optoisolator make it ideal for use in motor control, robotics, instrumentation, safety and alarm systems, and automotive applications. It can operate in temperatures ranging from –55°C to +125°C and come in various package styles including plastic small outline (SO) and quad flat no-lead (QFN).

The ACPL-847-000E optoisolator is also designed with an isolated ground plane that shields the photo detector. This ensures that its switching speed remains stable over temperature. To further increase its stability, the device offers a minimum input/output offset voltage of +1V.

In summary, the ACPL-847-000E optoisolator is a versatile, integrated device that is designed specifically for applications requiring electrical isolation between low voltage and high voltage circuits. It utilizes a dual LED array with a low input current and a high operating temperature range to allow a current flow of up to 100mA. The device\'s isolated ground plane and low minimum input/output offset voltage enable reliable and stable operation over a wide temperature range. The ACPL-847-000E optoisolator is available in a variety of package styles and is suitable for motor control, robotics, instrumentation, safety and alarm systems, and automotive applications.
