• Capacitive coupling technology providing high common-mode transient immunity
• Rail-to-rail output capability for efficient power switch control

Applications

• Automotive motor control systems
• On-board charger (OBC) gate drivers
• DC-DC converter isolation interfaces
• Industrial inverter drives

Procurement Notes

Verify the specific suffix (500E vs 000E) against the manufacturer's latest datasheet to ensure correct packaging and lead time specifications. Confirm RoHS3 compliance status directly with the supplier or authorized distributor prior to ordering. Ensure the procurement channel is authorized to guarantee component authenticity and traceability for automotive applications.

Selection Notes

Select this component when high-speed switching with robust noise immunity is required in automotive environments. The 10 A peak current supports direct driving of IGBTs and SiC MOSFETs. Verify that the system voltage levels align with the 10V to 25V output supply range. Consider the 24-SO package dimensions for PCB layout constraints compared to standard optocouplers.

Part Context

This part belongs to Broadcom's R2Coupler family, which replaces traditional optical isolation with capacitive coupling for improved reliability and speed. The ACFJ series is specifically engineered for harsh automotive electrical environments, offering superior common-mode rejection ratios compared to legacy phototransistor-based isolators.

Replacement Considerations

Direct pin-compatible replacements are limited due to the proprietary R2Coupler architecture. Review alternative gate driver isolators from Texas Instruments or Infineon only if they match the 10A peak current and 5kVrms isolation requirements. Validate functional equivalence thoroughly before substitution.
