Overview
The NTMS4503NR2G-001 is a single N-channel PowerTrench MOSFET manufactured by onsemi. It features a 28V drain-source voltage rating and a continuous drain current of 14A at 25°C. The device utilizes an 8-SOIC surface-mount package with a lead-free, halogen-free construction compliant with RoHS standards. Key electrical characteristics include a maximum on-resistance of 9.3mΩ at Vgs=10V and a gate charge of 14nC. The component operates within a temperature range of -55°C to +150°C junction temperature.
Feature Summary
- PowerTrench technology for low on-resistance
- Lead-free and halogen-free construction
- RoHS compliant manufacturing process
Applications
- DC-DC converter output stages
- Load switching applications
- Power management circuits
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the requested part number matches the exact electrical ratings and package outline required for the design. Cross-reference the manufacturer's latest datasheet revision to validate all parameters before finalizing procurement orders.
Selection Notes
Select this component based on its 28V voltage rating and 14A current capability for low-voltage power applications. Ensure the 8-SOIC package fits the PCB layout constraints. Verify thermal requirements against the 930mW power dissipation rating at ambient conditions. Compare the 9.3mΩ on-resistance against system efficiency targets to confirm suitability for the intended load.
Part Context
This part belongs to the NTMS4503 series of N-channel MOSFETs from onsemi. The series is characterized by PowerTrench technology designed for high-efficiency switching applications. The standard NTMS4503NR2G designation refers to the same core device, with variations typically limited to packaging or reel specifications rather than functional differences.
Replacement Considerations
Direct substitutes must match the 28V/14A/N-Channel specification and 8-SOIC package. Check equivalent parts from other manufacturers for compatible Rds(on) and Qg values. Verify pinout compatibility and thermal performance metrics before substitution.
