NIF5003NT1G

Overview

The NIF5003NT1G is a single N-channel power MOSFET manufactured by onsemi, housed in a SOT-223 surface-mount package. It features a drain-source breakdown voltage of 42 V and supports a continuous drain current of 14 A. The device exhibits a maximum on-resistance of 53 mΩ at a gate-source voltage of 10 V. It operates within a temperature range from -55 °C to +150 °C and has a power dissipation rating of 1.25 W.

Feature Summary

• Integrated self-protection circuitry providing thermal shutdown and current limiting capabilities
• Enhanced mode operation for direct logic interface compatibility
• Low on-resistance design optimized for efficient power switching applications

Applications

• Power supply load switching
• Inductive load control circuits
• Motor drive protection stages

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and protection feature alignment. Confirm moisture sensitivity level handling requirements during assembly. Ensure thermal management solutions match the specified power dissipation limits under actual operating conditions.

Selection Notes

Select this component when integrated overcurrent and thermal protection are required without external sensing components. Evaluate the trade-off between the low on-resistance and the package thermal resistance for high-current duty cycles. Compare against standard MOSFETs if discrete protection adds unnecessary complexity or cost.

Part Context

This part belongs to the NIF series of self-protected FETs designed for robust industrial and consumer applications. It combines standard MOSFET performance with built-in safety mechanisms, simplifying system design by reducing component count and board space compared to discrete protection schemes.
