NIS6420MT2TWG

Current Regulation/Management Overview

The NIS6420MT2TWG is a self-resettable PPTC electronic fuse manufactured by onsemi, designed for circuit protection. It features a maximum voltage rating of 15 VDC and a hold current of 2.2 A, with a trip current of 3.1 A. The device exhibits a typical resistance of 82 mOhms and operates within a temperature range of -40°C to +125°C. Packaged in a WQFN-12 surface-mount format, it provides reliable overcurrent protection for sensitive electronics.

Current Regulation/Management Feature Summary

• Self-resetting polymeric positive temperature coefficient (PPTC) technology for automatic recovery after fault clearance
• Integrated electronic fuse functionality providing overcurrent protection without manual replacement
• Surface-mount WQFN-12 package optimized for PCB space efficiency and automated assembly

Current Regulation/Management Applications

• Protection of hard disk drives against catastrophic failure
• Overcurrent safeguarding for general electronic circuits
• Prevention of shutdown faults in portable devices

Current Regulation/Management Procurement Notes

Verify the complete part number including the suffix TWG to ensure correct packaging and material compliance. Confirm that the required hold current and voltage ratings align with the specific circuit design requirements before procurement. Check for RoHS compliance status if environmental regulations apply to the final product assembly.

Current Regulation/Management Selection Notes

Select this component when a resettable protection mechanism is preferred over traditional fuses to minimize maintenance downtime. Ensure the operating environment stays within the specified -40°C to +125°C range. Consider the 82 mOhms resistance impact on power loss during normal operation compared to lower-resistance alternatives.

Current Regulation/Management Part Context

This device belongs to the NIS64x2 series of self-resettable electronic fuses from onsemi. It shares functional similarities with other models in the family but differs in specific electrical parameters such as hold current and resistance values tailored for different load capacities.

Current Regulation/Management Replacement Considerations

NIS6452MT2TWG offers higher current capacity. NIS6420 variants may exist with different suffixes indicating packaging differences. Verify pin compatibility and thermal characteristics when substituting.
