SMD2920P150TSA

Ptc Resettable Fuses Overview

The Littelfuse SMD2920P150TSA is a surface-mount polymer positive temperature coefficient (PPTC) resettable fuse from the PolySwitch family. Designed for overcurrent protection, this component features a hold current of 1.5 A and a maximum voltage rating of 6 VDC. It trips at a current of 3.0 A and supports a maximum fault current of 40 A. The device exhibits a typical resistance of 85 mOhms and operates within a temperature range of -40°C to +85°C. Packaged in a 2920 (7450 metric) SMD form factor with dimensions of 6.73 mm x 4.8 mm x 1.25 mm, it utilizes tin-plated copper terminals for soldering.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit recovery after fault conditions without manual replacement
• Offers reliable overcurrent protection through rapid resistance increase upon heating
• Compatible with standard high-temperature soldering processes for surface mount assembly

Ptc Resettable Fuses Applications

• Protection of portable electronic devices and battery packs

Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix 'TSA' matches the required tape-and-reel packaging configuration for automated assembly lines. Confirm RoHS compliance status and moisture sensitivity level requirements against your manufacturing process specifications before finalizing orders.

Ptc Resettable Fuses Selection Notes

Select this component when low operating voltage and moderate hold current are required for compact PCB layouts. Ensure the application current remains below the 1.5 A hold threshold while accounting for ambient temperature derating curves to prevent nuisance tripping during normal operation.

Ptc Resettable Fuses Part Context

This part belongs to the Littelfuse PolySwitch PPTC series, which serves as a solid-state alternative to traditional fuses. The 2920 package size balances board space efficiency with adequate current handling capabilities for general electronics protection applications.

Ptc Resettable Fuses Replacement Considerations

Cross-reference with other 2920-series PPTCs from Littelfuse or compatible manufacturers offering identical 1.5 A hold current and 6 VDC ratings. Verify dimensional tolerances and terminal plating compatibility to ensure seamless integration into existing footprints.
