NTA4153NT1H

Overview

The NTA4153NT1H is an N-channel enhancement mode MOSFET from onsemi, designed for surface-mount applications in the SC-75 package. It features a drain-source voltage (Vds) of 20 V and a continuous drain current (Id) of 915 mA at 25°C. The device includes built-in ESD protection and has a maximum power dissipation of 300 mW. Key electrical parameters include a gate-source threshold voltage of 1.1 V @ 250 uA and a typical on-resistance (Rds(on)) of 230 mΩ @ 600 mA, 4.5 V.

Feature Summary

• N-channel enhancement mode MOSFET with integrated ESD protection
• Low Rds(on) for improved system efficiency
• Low threshold voltage for compatibility with low-voltage logic

Applications

• Battery protection circuits
• Power management systems
• Signal switching applications

Procurement Notes

Verify the specific suffix 'H' against official onsemi documentation to confirm tape-and-reel quantity or variant specifications, as standard datasheets often list 'T1G'. Ensure the component matches the SC-75 package outline and pin configuration required for your PCB layout. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity.

Selection Notes

Select this component for low-voltage, low-current switching tasks requiring compact packaging. The 20 V rating suits single-cell battery applications. Verify that the 915 mA current limit meets load requirements and that the thermal performance of the SC-75 package is sufficient for the expected power dissipation under operating conditions.

Part Context

This part belongs to the NTA series of small signal MOSFETs from onsemi. These devices are engineered for high-density circuit designs where space is limited. The NTA4153 variant specifically targets applications needing efficient switching with minimal voltage drop, leveraging the SC-75 footprint for reliable surface-mount assembly.

Replacement Considerations

Check for direct substitutes like NTA4153NT1G if the 'H' suffix denotes a specific reel size rather than a functional change. Ensure any replacement maintains the 20 V Vds, 915 mA Id, and SC-75 package dimensions to fit existing footprints without redesign.
