NTS4172NT1G

Single FETs, MOSFETs Overview

The NTS4172NT1G is a single N-channel enhancement mode Power MOSFET from onsemi, designed for surface-mount applications. It features a maximum drain-source voltage (Vds) of 30 V and a continuous drain current (Id) of 1.6 A to 1.7 A. The device utilizes an SC-70 (SOT-323) package with three pins. Key electrical parameters include a typical gate charge (Qg) of approximately 5 nC at Vgs = 4.5 V and a maximum on-resistance (Rds(on)) of 180 mΩ at Vgs = 4.5 V. It operates within a temperature range of -55°C to +150°C junction temperature.

Single FETs, MOSFETs Procurement Notes

Verify the specific suffix and tape/reel quantity when ordering, as packaging configurations may vary by region or distributor. Confirm that the component meets the required AEC-Q101 grade if used in automotive contexts. Ensure the selected variant matches the exact pinout and thermal specifications for your PCB layout. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement contracts.

Single FETs, MOSFETs Selection Notes

Select this component for applications requiring a compact N-channel switch with 30 V breakdown and moderate current handling up to 1.7 A. Compare Rds(on) values against system loss budgets to ensure efficiency targets are met. Consider the SC-70 footprint constraints and thermal dissipation capabilities relative to the expected duty cycle. Verify compatibility with standard logic-level gate drivers operating at 3.3 V or 5 V.
