NIF5003NT3

Overview

The NIF5003NT3G is a single N-Channel enhancement mode MOSFET manufactured by onsemi. It utilizes silicon technology and is housed in an SMD/SMT SOT-223-3 package. Key electrical parameters include a drain-source breakdown voltage (Vds) of 42 V, a continuous drain current (Id) of 14 A, and a maximum gate-source voltage (Vgs) of 14 V. The device features a low on-resistance (Rds On) of 53 mOhms and a power dissipation (Pd) rating of 1.25 W. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Single N-Channel enhancement mode configuration for efficient switching control
• Low on-resistance design to minimize conduction losses
• Robust thermal performance with high junction temperature capability

Applications

• Power management circuits
• Load switch applications
• Motor drive systems

Procurement Notes

Verify the specific ordering suffix, as 'NIF5003NT3' may refer to the base part number while commercial availability often requires the 'G' suffix indicating RoHS compliance. Confirm moisture sensitivity levels and reel packaging quantities directly with the manufacturer or authorized distributors prior to procurement. Ensure the component meets all required environmental and safety standards for the intended deployment environment.

Selection Notes

Select this component when a compact SOT-223 footprint is required for moderate current switching applications up to 14 A. The 42 V rating suits low-voltage DC bus systems. Evaluate thermal management requirements given the 1.25 W power dissipation limit in the specified package. Ensure gate drive voltages remain within the 14 V maximum rating to prevent device damage.

Part Context

This component belongs to the NIF5003N series of N-Channel MOSFETs from onsemi. It is designed for general-purpose switching tasks where space constraints and efficiency are priorities. The SOT-223-3 package provides a balance between current handling capability and board space savings compared to larger through-hole packages.
