ACPL-W481-560E

Overview

The ACPL-W481-560E is a single-channel logic-output optocoupler manufactured by Broadcom Limited. It features a push-pull totem pole output configuration and is housed in a 6-pin SO stretched package. The device provides an isolation voltage of 5000 Vrms and supports a common mode transient immunity of 20 kV/µs. Key electrical parameters include a forward voltage of 1.5 V, a supply voltage range of 4.5 V to 20 V, and an operating temperature range from -40°C to +100°C. The component incorporates a built-in Schmitt trigger for signal integrity.

Feature Summary

• Integrated push-pull totem pole output stage for robust signal driving
• Built-in Schmitt trigger input for noise immunity and clean switching
• High common mode transient immunity capability for noisy environments

Applications

• Gate drive isolation for power electronics
• Industrial control system signal interfacing
• Inverter and converter circuit protection

Procurement Notes

Verify the specific ordering suffix matches the required packaging format, as variations exist between tube and tape-and-reel configurations. Confirm that the 6-pin SO stretched package dimensions align with the target PCB footprint. Ensure the selected variant meets the necessary insulation coordination standards for the intended application safety requirements.

Selection Notes

Select this component when high-speed digital isolation with strong output drive is required. The totem pole output eliminates the need for external pull-up resistors, simplifying circuit design. Consider the 5000 Vrms isolation rating for applications requiring enhanced safety barriers. Verify that the 20 kV/µs CMTI specification satisfies the electromagnetic interference constraints of the system.

Part Context

This part belongs to the ACPL-W series of logic-output optoisolators designed for demanding industrial applications. It complements other Broadcom optocouplers by offering faster response times and higher immunity compared to standard transistor-output devices. The series focuses on reliability in high-noise power conversion environments.

Replacement Considerations

Direct substitutes may include other single-channel logic-output optocouplers with similar 5000 Vrms isolation and push-pull outputs. Verify pinout compatibility and package dimensions before substitution. Check datasheets for equivalent CMTI ratings and output current capabilities to ensure functional parity.
