ZXCT1083E5TA

Overview

The ZXCT1083E5TA is a high-side current monitor manufactured by Diodes Incorporated, designed for precise current sensing in power management applications. It operates within an input voltage range of 2.7V to 40V and features a low quiescent current of 600nA. The device is housed in a compact SOT-25 (SC-74A) surface-mount package, suitable for space-constrained designs. Certified to AEC-Q100 standards, it ensures reliability for automotive environments with an operating temperature range spanning from -40°C to +125°C.

Feature Summary

• High-side current monitoring capability for accurate load current measurement
• Automotive-grade qualification ensuring robust performance in harsh environments
• Ultra-low quiescent current consumption for enhanced energy efficiency
• Compact SOT-25 surface-mount packaging for optimized board space utilization

Applications

• Automotive battery monitoring systems
• Current limiting protection circuits
• Power distribution unit (PDU) control
• Battery charger current regulation

Procurement Notes

Verify the specific suffix E5TA corresponds to the standard SOT-25 package variant when sourcing. Confirm AEC-Q100 certification requirements align with target automotive or industrial specifications. Check RoHS3 compliance status for environmental regulations. Ensure supply chain sources provide official datasheets matching the Diodes Incorporated part number to avoid counterfeit components.

Selection Notes

Select this component when high-side sensing is required within a 40V maximum input limit. Consider the 600nA quiescent current for battery-powered applications where standby power is critical. The SOT-25 package offers a balance between thermal performance and footprint size. Verify that the ±2% accuracy specification meets the system's tolerance requirements compared to other variants in the ZXCT108x series.

Part Context

This part belongs to the ZXCT108x series of current monitors from Diodes Incorporated. It shares functional similarities with the ZXCT1082 and ZXCT1085 but differs in input voltage ranges and precision levels. The E5TA suffix denotes the specific tape-and-reel packaging configuration for automated assembly processes.

Replacement Considerations

ZXCT1082QE5TA offers higher voltage tolerance up to 60V. ZXCT1085E5TA provides similar 40V operation with potentially different accuracy characteristics.
