NID5003NT4G

Overview

The NID5003NT4G is a single N-Channel Power MOSFET manufactured by onsemi, designed for high-current switching applications. It features a 42 V drain-source breakdown voltage and supports a continuous drain current of 20 A. The device incorporates self-protection mechanisms, including thermal shutdown and current limiting, to enhance system reliability under fault conditions. Packaged in the DPAK (TO-252) surface-mount format, it offers low on-resistance for efficient power management. The component operates within a junction temperature range of -55°C to +150°C and is RoHS compliant.

Feature Summary

• Integrated self-protection circuitry providing thermal shutdown and current limit capabilities
• Single N-Channel enhancement mode construction for efficient switching
• Surface-mount DPAK package optimized for automated assembly

Applications

• High-side or low-side power switching in automotive systems
• Load control modules requiring overcurrent protection
• Power distribution units with thermal safety requirements

Procurement Notes

Verify the specific suffix 'G' confirms RoHS compliance and halogen-free status as per onsemi standards. Confirm the package variant matches the required DPAK footprint. Check for obsolescence notices or lifecycle status updates directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when design requirements demand integrated fault protection rather than discrete external safeguards. Ensure the thermal management solution accommodates the power dissipation characteristics at the expected ambient temperatures. Verify that the gate drive voltage aligns with the specified threshold for optimal Rds(on) performance.

Part Context

This part belongs to onsemi's self-protected FET family, which integrates protection logic directly into the silicon die. Unlike standard MOSFETs, these devices simplify board layout by reducing the need for external sensing resistors and control ICs. The NID5003NT4G specifically targets applications where space constraints and reliability are critical factors.

Replacement Considerations

Direct substitutes include NID5003NT4 and NID5003NT4G. Verify pinout compatibility and ensure the replacement maintains the same self-protection functionality and thermal characteristics.
