ACPL-K75T-500E

Overview

The ACPL-K75T-500E is a dual-channel automotive-grade digital optocoupler from Broadcom Limited. It features a push-pull totem pole output configuration and provides 5000 Vrms isolation voltage. The device offers high common-mode transient immunity of 25 kV/µs, ensuring reliable signal transmission in electrically noisy environments. Qualified to AEC-Q100 standards, it operates within a temperature range of -40°C to +125°C. Packaged in an 8-pin SOIC (SSO) surface-mount format, this component is designed for robust performance in demanding automotive applications requiring galvanic isolation.

Feature Summary

• Dual-channel architecture with push-pull totem pole outputs for enhanced drive capability
• High common-mode transient immunity of 25 kV/µs for noise resilience
• Automotive qualification compliant with AEC-Q100 reliability standards
• Wide operating temperature range suitable for harsh automotive environments

Applications

• Automotive battery management systems
• Electric vehicle motor control units
• Charging station interfaces
• Inverter gate driver circuits

Procurement Notes

Verify the specific suffix '500E' matches the required RoHS compliance and tape-and-reel packaging specifications. Confirm that the AEC-Q100 qualification status aligns with your project's automotive reliability requirements. Ensure the 8-pin SSO package dimensions fit your PCB layout constraints. Cross-reference the manufacturer's latest datasheet for any updates on recommended operating conditions or thermal derating curves before finalizing procurement.

Selection Notes

Select this component when dual-channel isolation with high-speed switching and strong noise immunity is required. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design. Consider the 5000 Vrms isolation rating for safety-critical applications. The wide temperature range makes it suitable for under-hood or powertrain locations where standard commercial components may fail.

Part Context

This part belongs to Broadcom's ACPL-R2Coupler series, which focuses on high-performance automotive isolation solutions. The series is engineered to meet the stringent demands of modern electric and hybrid vehicles. The ACPL-K75T-500E specifically targets applications needing robust galvanic isolation between low-voltage control logic and high-voltage power stages.

Replacement Considerations

Check for direct pin-compatible alternatives within the ACPL-K75 family. Verify if single-channel variants can be used if only one channel is needed. Ensure any substitute maintains the same 25 kV/µs CMTI rating and AEC-Q100 qualification to preserve system reliability and certification status.
