Optoisolators are a type of solid-state electronic component used to electrically isolate two different circuits by using light. The ACPL-847-W60E is a specific type of optoisolator known as a transistor photovoltaic output. It is designed to provide a safe and highly reliable means of isolating and protecting sensitive circuitry from high-voltage spiking and electrical anomalies.

The ACPL-847-W60E optoisolator integrates a phototransistor detector and an optically coupled voltage regulator in a single package. This is done to provide an isolation barrier between circuits while maintaining high-reliability signal integrity. The device is made up of an LED and a phototransistor with a high-voltage integrated regulator connected to the output. The device typically operates up to an isolation voltage of 6,000 V RMS.

The optoisolator functions by requiring input power to light up the LED, which in turn energizes the phototransistor. This forms a circuit with a current amplifier, which is then passed on to the integrated integrated voltage regulator. This regulator is responsible for keeping the voltage to the output side at a constant level regardless of the voltage on the input side. The output of the regulator is sent to the output, completing the isolation barrier between the two circuits.

Compared to other optoisolator types, the ACPL-847-W60E provides an exceptionally low turn-on voltage, allowing it to operate in extremely low input voltages. The device also features an integrated surge protection of over 200W, which makes it highly resistant to interference from obstacles such as lightning strikes and voltage surges.

The main application field of the ACPL-847-W60E optoisolator is industrial automation systems, where it is used to isolate the signals sent between field devices such as sensors, actuators, and communication links. The device is also widely used in consumer electronics, telecommunications systems, process control systems, and medical instruments.

The ACPL-847-W60E optoisolator provides high-speed signal transfer, low power consumption, good reliability, and high accuracy. It is highly effective in providing electrical isolation between two circuits while maintaining high integrity of the signals. The device is also highly resistant to electrical anomalies, such as voltage spikes, electromagnetic interference, and board level crosstalk. Overall, the ACPL-847-W60E provides a reliable and highly effective way to ensure electrical safety and signal integrity in industrial automation and other circuits.
