ACPL-W70L-060E

Optoisolators, also referred to as opto-couplers, are electronic devices used to transfer electrical signals between two isolated circuits while the electrical elements remain electrically separate. Optoisolators - Logic Output devices are photovoltaic (PV) components designed to transmit digital signals across an isolation barrier, such as ACPL-W70L-060E.

The ACPL-W70L-060E utilizes a low-power GaAsP LED, which is optically coupled to an integrated circuit with a photodetector. The LED is driven by the electrical signal from the input side, allowing the photodetector to trigger the switch on/off action on the output side. This device offers several advantages over other types of optoisolators, including a low power consumption, high common-mode transient immunity, and a low switch ON resistance.

The ACPL-W70L-060E is widely used in various applications, such as industrial and automotive fields. It is suitable for applications such as process control, factory automation, and home automation. In automotive applications, it is used in electronically-controlled (ECU) systems for fuel injection, engine control, and emissions control.

The ACPL-W70L-060E has several features that make it particularly well-suited for applications requiring reliable isolation of both low voltage and high voltage voltages. A key feature is its high common-mode transient immunity, which makes it resistant to spurious electrical interference. Additionally, its low power consumption and low switch ON resistance make it energy efficient, which is beneficial for devices that require long-term operation.

The working principle of the ACPL-W70L-060E is straightforward. The absence of any direct conduction between input and output terminals creates a virtual electrical barrier that blocks any potentially destructive electrical signals from passing from one side to the other. This barrier is created by the optical component that is incorporated within the ACPL-W70L-060E, and it is visible due to the presence of light-producing elements, such as LEDs and photodiodes.

The LEDs on the input side of the ACPL-W70L-060E have the property of converting electrical signals into sensory light signals which are then transferred to the photodiodes on the output side. When the right frequency of light is emitted, it triggers the photodiodes to create a switch on/off action.

The ACPL-W70L-060E is a highly reliable optoisolator that is ideal for applications requiring reliable and electrically-isolated digital signals. Its low power consumption and high common-mode transient immunity make it a suitable option for many automated systems, and its proven performance in industrial and automotive applications testifies to its wide-ranging applicability.
