NTTFS5C673NLTWG

NTTFS5C673NLTWG Description

The NTTFS5C673NLTWG from onsemi is a high-performance N-channel MOSFET designed for demanding power management applications. With a 60V drain-to-source voltage (Vdss) and low on-resistance (Rds(on)) of 9.3mΩ at 25A, 10V, this device offers superior efficiency in switching and power conversion circuits. It supports continuous drain currents (Id) of 13A (ambient) and 50A (case-cooled), making it suitable for high-current applications. Packaged in an 8-pad WDFN (8WDFN) with surface-mount compatibility, it is optimized for compact PCB designs.

NTTFS5C673NLTWG Features

• Low Gate Charge (Qg): 9.5nC @ 10V minimizes switching losses, enhancing efficiency in high-frequency applications.
• Robust Power Handling: 3.1W (Ta) / 46W (Tc) power dissipation ensures reliable thermal performance.
• Wide Drive Voltage Range: Operates efficiently with 4.5V to 10V gate drive, compatible with modern logic-level controllers.
• Fast Switching: Low input capacitance (Ciss) of 880pF @ 25V reduces transition delays.
• Reliability: ROHS3 compliant, REACH unaffected, and MSL1 (unlimited) moisture sensitivity for long-term durability.
• Last-Time-Buy Status: Ideal for legacy designs requiring proven performance.

NTTFS5C673NLTWG Applications

This MOSFET excels in:

• DC-DC Converters: High efficiency and low Rds(on) minimize power loss in step-down/step-up topologies.
• Motor Control: Robust current handling (50A @ Tc) suits brushed/brushless motor drivers.
• Power Management in Automotive/Industrial Systems: Withstands harsh environments due to high Vgs(max) (±20V) and thermal resilience.
• Battery Protection Circuits: Low gate threshold (Vgs(th) = 2V @ 250µA) ensures precise control in portable electronics.
• Load Switches & Hot-Swap Controllers: Fast switching and low conduction losses improve system response.
