PSMNR98-25YLEX-VB Product details
Back to previous pageProduct introduction：
The PSMNR98-25YLEX-VB is a Single N-MOSFET deeply optimized for low-voltage, high-power switching applications. Using advanced SGT (Shielded Gate Trench) technology, it achieves an excellent balance between ultra-low on-resistance and high switching speed. The LFPAK56 package offers superior heat dissipation and low parasitic inductance, making it suitable for high-density current conversion and compact power system designs. The combination of 40V withstand voltage, 150A continuous current capability, and 0.7mΩ ultra-low on-resistance makes it an ideal upgrade option to replace traditional DPAK/D2PAK packages in low-voltage, high-current applications, especially for server power supplies, automotive electrical systems, and high-performance DC-DC modules.

VDS=40V: Suitable for 12V/24V/36V systems, with ample margin for switching voltage spikes, enhanced avalanche ruggedness, reducing system failure risk.
VGS=±20V: Compatible with standard gate drives and various PWM controllers, can be driven directly by driver ICs or logic circuits, simplifying peripheral design.
Vth=3V (typical): Moderate threshold voltage, effectively suppresses Miller plateau false turn-on, improves current sharing stability in multi-device parallel configurations.
RDS(on)=0.7mΩ @ VGS=10V: Ultra-low on-resistance, minimal full-load losses, significantly reduces temperature rise, enabling smaller heatsinks or higher power density.
ID=150A: Strong continuous current capability, confidently handles high-surge current scenarios like motor startup, battery short-circuit protection, and energy storage systems.
Package LFPAK56: Low thermal resistance, low parasitic inductance, supports high-frequency switching, saves PCB space, facilitating high-current trace layout.
Technology SGT: Shielded gate structure reduces Qgd/Qgs ratio, better EMI performance, lower switching losses, suitable for both hard-switching and soft-switching topologies.
Domain and module applications：
High-power DC-DC Converter: Replaces multiple parallel low-voltage MOSFETs in synchronous rectification applications; 0.7mΩ resistance significantly improves heavy-load efficiency, allowing further module size reduction.
Server and Telecom Power Supplies: Handles rectification or half-bridge switching in 48V/12V bus conversion; low loss and high thermal reliability meet long-term full-load operation requirements.
Automotive Electrical Systems: 40V withstand voltage covers 12V/24V vehicle bus transient overvoltage; 150A current capability supports main fuse bypass, electronic fuses, and high-power load switches.
Motor Drive and Control: Low on-resistance and high current output reduce winding drive losses; smooth PWM switching characteristics suit power tools, small electric vehicles, and drone ESCs.
Battery Protection and BMS: High current carrying capacity combined with low conduction voltage drop reduces protection board heat generation; suitable for high-rate charge/discharge scenarios like energy storage battery packs and portable power supplies.
UPS and Backup Power: Provides an efficient, low-loss path in inverter H-bridges or bypass switches, enhancing system overload and short-circuit withstand capability.
Low-Voltage High-Current Load Switch: Ideal for hot-swap, power path management, smart power distribution units, and other applications requiring extremely low voltage drop and high reliability. Selection Summary: The PSMNR98-25YLEX-VB, with its core advantages of 40V withstand voltage, 150A current, 0.7mΩ ultra-low on-resistance, and SGT technology, combined with the excellent heat dissipation and low parasitic characteristics of the LFPAK56 package, offers a highly competitive single-tube solution for high power density and high thermal challenge scenarios. Compared to traditional multi-tube parallel solutions, it effectively reduces parasitic parameter dispersion, simplifies PCB layout, and improves overall system reliability, making it a high-performance preferred model for low-voltage, high-current power switching and conversion applications.
