NIS6351MT2TXG

Current Regulation/Management Overview

The NIS6351MT2TXG is a PPTC resettable fuse manufactured by onsemi, designed for surface-mount PCB assembly. It features a maximum voltage rating of 5 VDC and a maximum rated current of 3 A. The device maintains a hold current of 2.2 A and trips at a trip current of 3.1 A. Its typical resistance is 85 mOhms. The component operates within a temperature range of -40°C to +125°C and is housed in a WDFNW-10 package.

Current Regulation/Management Feature Summary

• Provides automatic circuit protection through self-resetting functionality upon fault clearance
• Designed for surface-mount integration into printed circuit boards
• Operates reliably across extended industrial temperature ranges

Current Regulation/Management Applications

• Overcurrent protection for low-voltage electronic circuits
• Portable device power line safeguarding
• Consumer electronics input protection

Current Regulation/Management Procurement Notes

Verify the End-of-Life status before design finalization, as discontinuation notices indicate the manufacturer will cease production. Confirm RoHS compliance details via the official datasheet. Ensure the WDFNW-10 package footprint matches the target PCB layout. Validate that the 5 VDC rating aligns with system requirements.

Current Regulation/Management Selection Notes

Select this component when a compact, auto-retry protection solution is required for 5 VDC systems. The 2.2 A hold current suits moderate load applications. The WDFNW-10 package offers space efficiency. Verify thermal dissipation capabilities, as the device handles up to 1.3 W power dissipation during fault conditions.

Current Regulation/Management Part Context

This part belongs to the NIS6351 series of PPTC resettable fuses from onsemi. These devices serve as alternatives to traditional fusible links by offering reusable overcurrent protection. The series targets applications requiring reliable, low-profile circuit safeguarding without manual replacement after tripping events.
