ACPL-K72T-500E

Overview

The ACPL-K72T-500E is a high-speed digital CMOS optocoupler from Broadcom's ACPL-K series, designed for emerging electric vehicle applications. It features a single channel with logic output in an 8-pin SO stretched package. The device provides 5000Vrms isolation and 25kV/µs common-mode transient immunity (CMTI). It operates within a temperature range of -40°C to 85°C and complies with AEC-Q100 automotive standards.

Feature Summary

• High-speed digital CMOS architecture suitable for demanding automotive environments
• Integrated push-pull totem pole output stage for efficient signal transmission
• Advanced R2Coupler technology combining AlGaAs LED with high-gain photodetector

Applications

• Electric vehicle powertrain control systems
• High-voltage isolation interfaces in automotive electronics
• Automotive gate driver circuits requiring high CMTI

Procurement Notes

Verify the specific suffix '500E' matches your bill of materials, as it denotes the reel packaging configuration. Confirm that the 8-pin SO stretched package dimensions align with your PCB footprint requirements. Ensure the -40°C to 85°C operating range meets your system's thermal specifications. Cross-reference the AEC-Q100 compliance status if your application mandates strict automotive qualification standards.

Selection Notes

Select this component when high common-mode transient immunity is critical to prevent false triggering in noisy electric vehicle environments. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design. Consider the 5000Vrms isolation rating for safety-critical interfaces between low-voltage control logic and high-voltage power stages.
