Overview
The ACPL-K71T-500E is a single-channel logic output optocoupler manufactured by Broadcom Limited. It features a push-pull, totem pole output stage designed for high-speed digital isolation applications. The device provides an insulation voltage of 5000 Vrms and exhibits a common mode transient immunity of 15 kV/µs. It is housed in an 8-pin SO stretched package and supports automotive qualification standards.
Feature Summary
- Push-pull totem pole output configuration for fast signal transmission
- High common mode transient immunity rating for noise resilience
- Automotive grade qualification ensuring reliability in harsh environments
Applications
- Automotive electronic control units
- Industrial communication interfaces
- Motor drive isolation circuits
Procurement Notes
Verify the specific suffix and manufacturing date code against the latest official datasheet to ensure compliance with current automotive quality standards. Confirm that the 8-pin SO stretched package dimensions match your PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when high-speed digital isolation with robust noise immunity is required in automotive or industrial settings. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design compared to open-collector alternatives while maintaining high data rates.
Part Context
This part belongs to the ACPL series of high-speed optocouplers from Broadcom Limited. It is specifically engineered for applications requiring reinforced insulation and high reliability, distinguishing it from standard general-purpose optocouplers through its enhanced transient immunity and automotive certification.
Replacement Considerations
Direct substitutes include other single-channel automotive-grade optocouplers with similar 5000 Vrms isolation and push-pull outputs, such as the ACPL-K72T-500E for dual-channel needs or variants within the same Broadcom ACPL family offering comparable CMTI ratings.
