ACFL-6211T-000E

Overview

The ACFL-6211T-000E is an automotive-grade, dual-channel high-speed optocoupler designed for bi-directional digital communications. It features a push-pull totem pole output configuration and supports data rates up to 15 MBd. The device provides 5000 Vrms isolation voltage and offers common-mode transient immunity of 15 kV/µs. Qualified to AEC-Q100 Grade 1 standards, it operates with a forward current of 10 mA and delivers an output current of 8 mA. Packaged in a 12-SO (BSOP) surface-mount case, it ensures reliable signal transmission across isolated boundaries in demanding environments.

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging and tape-and-reel specifications. Confirm that the component meets the required AEC-Q100 Grade 1 qualification for your target application. Check the datasheet for exact thermal and electrical limits under operating conditions. Ensure compatibility with your system's voltage supply range of 3V to 5.5V. Validate the 12-SO package dimensions against your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when high-speed bi-directional communication is required in isolated circuits. The 15 MBd data rate suits applications needing rapid signal transfer. The 15 kV/µs CMTI rating makes it suitable for noisy industrial or automotive environments. Consider the dual-channel layout if multiple isolated signals must be transmitted simultaneously. Verify that the 5000 Vrms isolation level meets safety standards for your specific equipment class.

Part Context

This part belongs to Broadcom’s ACFL series of auto optocouplers. These devices are engineered for robust isolation in automotive and industrial sectors. The series emphasizes high speed and reliability, distinguishing itself from standard logic optoisolators through enhanced transient immunity and automotive qualification. The ACFL-6211T variant specifically targets applications requiring bidirectional data flow with high noise tolerance.

Replacement Considerations

The ACFL-6211T-060E and ACFL-6211T-500E are confirmed substitute part numbers within the same product family. These variants share identical electrical characteristics but differ in packaging quantities or reel specifications. Verify that the alternative suffix matches your manufacturing assembly requirements without altering functional performance.
