ZXCT1087QE5TA

Overview

The ZXCT1087QE5TA is a high-side current monitor manufactured by Diodes Incorporated, designed for automotive applications with AEC-Q100 qualification. It operates within an input voltage range of 2.7 V to 40 V and features a low quiescent current of 600 nA. The device provides accurate current sensing in a compact SOT-25 package, suitable for surface-mount installation across a temperature range of -40°C to +125°C.

Feature Summary

• High-side current monitoring capability
• Automotive grade reliability certification
• Low power consumption design

Applications

• Automotive battery management systems
• High-side load switching protection
• Current limiting in vehicle electronics

Procurement Notes

Verify the specific suffix E5TA corresponds to the required packaging format, such as cut tape or reel, as distributor listings may vary. Confirm AEC-Q100 compliance is explicitly stated for the exact part number variant being ordered. Check for any recent product change notifications regarding leadframe materials or bond wire composition that might affect long-term sourcing stability.

Selection Notes

Select this component when a 40 V maximum input voltage limit is sufficient for the application, distinguishing it from higher voltage variants like the ZXCT1086 series. Ensure the SOT-25 package footprint aligns with the PCB layout constraints. Consider the 600 nA quiescent current if ultra-low standby power is critical compared to other monitors in the family.

Part Context

This part belongs to the ZXCT108x series of high-side current monitors from Diodes Incorporated. It shares functional similarities with models like the ZXCT1083E5TA but offers a different input voltage range. The series is characterized by its automotive qualification and compact SOT-25 packaging, targeting robust industrial and automotive environments.

Replacement Considerations

The ZXCT1083E5TA serves as a similar alternative within the same series, though it shares the same 40 V input limit. For higher voltage requirements, the ZXCT1086QE5TA is the appropriate substitute, supporting up to 60 V. Verify pin compatibility and accuracy specifications before swapping.
