Broadcom ACPL-847-30GE High-Speed Optocoupler for Industrial and Automotive Applications

In the demanding environments of industrial automation and modern automotive systems, ensuring reliable signal isolation is critical to both performance and safety. The Broadcom ACPL-847-30GE is a high-speed optocoupler engineered to meet these rigorous demands, offering robust noise immunity, high voltage isolation, and exceptional reliability.

This optocoupler integrates a GaAlAs LED optically coupled with a high-speed integrated photodetector. It is designed to support data rates up to 30 MBd, making it suitable for high-frequency communication interfaces such as PWM motor control, PLC I/O modules, and isolated serial data transmission. Its high common-mode rejection (CMR) capability ensures stable performance even in electrically noisy environments, such as factory floors or automotive powertrains.

A key feature of the ACPL-847-30GE is its wide operating temperature range from -40°C to 125°C, which qualifies it for use in extreme conditions typical in automotive under-hood applications or industrial outdoor equipment. Additionally, it complies with international safety standards including UL1577, IEC/EN 60747-5-5, and VDE0884-11, providing reinforced isolation up to 5 kV RMS.

The device is available in a compact SO-5 package, facilitating high-density PCB layouts while maintaining superior creepage and clearance distances. Its low power consumption and high-speed performance make it ideal for hybrid/electric vehicle battery management systems, isolated gate drivers, and industrial network interfaces.
