ACPL-W70L-500E

Overview

The ACPL-W70L-500E is a single-channel high-speed CMOS optocoupler manufactured by Broadcom Limited. It features a push-pull, totem pole output configuration designed for robust digital signal transmission. The device provides an isolation voltage of 5000 Vrms and supports data rates up to 15 MBd. Key electrical parameters include a common-mode transient immunity (CMTI) of 10 kV/µs, ensuring reliable operation in noisy environments. The component is housed in a 6-pin Small Outline package.

Feature Summary

• High-speed CMOS technology enabling rapid signal propagation
• Push-pull output stage for strong drive capability
• High common-mode transient immunity for noise rejection

Applications

• Industrial automation control systems
• Power supply feedback loops
• Data communication interfaces

Procurement Notes

Verify the specific suffix against official datasheets to confirm isolation ratings and packaging options. Ensure compatibility with existing PCB footprints and thermal management requirements. Confirm that the selected variant meets all necessary regulatory certifications for the target application environment.

Selection Notes

Select this component when high-speed digital isolation is required alongside significant noise immunity. The push-pull output is suitable for driving low-impedance loads directly. Evaluate the CMTI specification against the expected noise levels in the system to ensure signal integrity during fast switching events.

Part Context

This part belongs to the ACPL-W70L series, which includes both single and dual-channel variants. The series is characterized by its use of advanced CMOS processes to achieve high bandwidth within standard small outline packages. It serves as a modern replacement for older transistor-output optocouplers in high-performance applications.
