Optoisolators are widely used in various applications and systems for interfacing and protecting circuits from high-voltage, noise, electromagnetic interference, and other signals. The ACPL-K71T-500E is a single-channel, high-performance logic output optoisolator designed to provide high-current output stages to meet the needs of higher power applications. The device has a wide range of output current levels choose from and it is also RoHS-compliant to minimize environmental impact.

The ACPL-K71T-500E is ideal for isolated communication applications such as I2C bi-directional between components, serial interfaces, and PLC/Printer interface connecting. It features an operating temperature range from -40°C to +85°C, an operating supply voltage between 4.5V and 5.5V, and a wide operating supply range from 4.5V to 36V.

The ACPL-K71T-500E’s optical-electrical isolation removes ground loops, surges, and transients, which protects the sensitive low voltage circuits from damage. It provides 460mW power rating per channel, 3.75××4.32mm SMT package, 1.5kV I/O isolation voltage, and CMTI of up to 30kV/μs. The device is also designed to meet the industrial-level safety requirements.

The ACPL-K71T-500E is designed to meet the industrial-level performance requirements. It consists of an infrared emitter and an integrated photo detector. The optoisolator uses the principle of electrical isolation to transfer data across the interface. The internal isolation barrier between the input and output circuits isolates the two circuits electrically, which prevents any interference from the input circuit to the output circuit.

When the input signal is provided, the LED sends out light pulses. The light emitted by the LED then travels to the integrated photodetector and is converted to an electric signal. This electric signal is then amplified by the output transistor and is used to drive the output circuit. The output signal is then amplified and used to control various components in the application.

The ACPL-K71T-500E has wide range of current isolating levels which makes it suitable for a variety of applications. It has a high optical isolation which prevents ground loop problems and surge transients. Its low power consumption also helps to extend the lifetime of the device, while its wide operating temperature range of -40°C to +85°C makes it suitable for industrial-level applications.

In summary, the ACPL-K71T-500E is a highly reliable and efficient optoisolator that offers great performance in isolated communication applications such as I2C bi-directional between components, serial interfaces, and PLC/Printer interface connecting. Its wide range of output current levels, high optical isolation, low power consumption, and wide operating temperature range make it an ideal choice for industrial applications. It is also RoHS compliant, which helps to reduce electronic waste and ensure environmental protection.
