ACFJ-3262T-000E

Overview

The ACFJ-3262T-000E is a dual-channel automotive-grade logic output optocoupler manufactured by Broadcom Limited. It features an SO-24 surface-mount package and provides 5000 Vrms insulation voltage for robust signal isolation. The device operates with a forward current of 10 mA and a forward voltage of 1.55 V, supporting a reverse voltage of 6 V. Key timing parameters include a rise time of 7 ns and a fall time of 7 ns, enabling high-speed switching capabilities suitable for demanding automotive environments.

Feature Summary

• Dual-channel architecture providing independent signal isolation paths within a single compact package.
• Automotive qualification ensuring reliability under rigorous environmental and operational conditions.
• High-speed switching performance with nanosecond-level rise and fall times for efficient data transmission.
• Robust electrical isolation capability to protect sensitive control circuits from high-voltage noise.

Applications

• Advanced Driver Assistance Systems (ADAS) requiring isolated sensor interfaces
• Electric powertrain control modules for battery management systems
• Chassis control units needing reliable communication between low and high voltage domains

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing components. Confirm that the automotive grade designation aligns with project-specific quality standards. Ensure compatibility with SO-24 footprint requirements during PCB layout finalization. Check for any recent product change notifications regarding material composition or manufacturing site updates.

Selection Notes

Select this component when dual-channel isolation is required in space-constrained automotive applications. The 7 ns switching speed supports higher frequency communication protocols compared to standard optocouplers. Consider the SO-24 package dimensions against available board real estate. Evaluate the 5000 Vrms isolation rating against system safety requirements and regulatory compliance needs.

Part Context

This part belongs to Broadcom's automotive optocoupler portfolio, designed specifically for vehicle electrification and autonomous driving technologies. It addresses the need for reliable signal transfer in electric powertrains and chassis control systems where electromagnetic interference is prevalent.

Replacement Considerations

Consult official Broadcom documentation for qualified alternative part numbers within the ACPL or ACFJ series. Verify pinout compatibility and electrical parameter equivalence before substitution. Ensure any replacement maintains the same automotive qualification status and package type.
