PML340SN,118-VB is a Single N-MOSFET optimized for high-voltage power switching applications. Using SGT (Split-Gate Trench) technology, it achieves a good balance between switching speed, conduction loss, and avalanche ruggedness. The DFN8(3X3) package offers both a compact footprint and excellent heat dissipation, making it suitable for high-density power conversion and industrial control applications. The combination of 200V voltage rating, 10A current capability, and 145mΩ on-resistance makes it a reliable choice for medium and low-power high-voltage switches, auxiliary power supplies, and motor drives.
()- **VDS=200V**: Suitable for 48V~120V bus systems and industrial bus voltages, providing ample margin for voltage spikes, significantly reducing drain overvoltage breakdown risk, ideal for inductive load switching scenarios. - **VGS=±20V**: Wide gate drive window, compatible with 5V~15V common drive levels, can be driven directly by PWM controllers, gate driver ICs, or MCUs, simplifying peripheral design. - **Vth=3V (Typical)**: Moderate threshold voltage, balancing anti-interference capability and drive compatibility, enters full conduction region under 10V drive, preventing false turn-on. - **RDS(on)=145mΩ @ VGS=10V**: Optimized on-resistance, controllable full-load loss, combined with the bottom-side thermal pad of the DFN8(3X3) package, effectively reduces temperature rise, enhancing system reliability. - **ID=10A**: Ample continuous drain current margin to handle typical motor stall, capacitive load surge, or short-circuit transient peaks. - **Package DFN8(3X3)**: Small size, low parasitic inductance, supports high-frequency switching, saves PCB area; with copper-clad thermal design, thermal resistance is superior to traditional packages of the same size. - **Technology SGT**: Split-Gate Trench structure reduces Miller capacitance, resulting in lower switching loss, suitable for high-frequency hard-switching or soft-switching topologies.
Domain and module applications：
- **Industrial Auxiliary Power Supplies**: 200V withstand voltage covers three-phase rectified bus; SGT technology reduces switching losses, improving light-load efficiency, suitable for flyback, forward, and LLC auxiliary winding circuits. - **DC-DC Converters**: Used as main switches in high-voltage step-down (e.g., 48V→12V) or boost topologies; low \(Q_{gd}\) reduces duty cycle loss, aiding module miniaturization. - **Motor Drives and Inverter Control**: 10A current capability matches hundred-watt-level BLDC/PMSM drives; 145mΩ internal resistance reduces winding power loss; DFN8 packaging facilitates compact three-phase bridge layout. - **Solar Photovoltaic Optimizers / Microinverters**: 200V withstand voltage adapts to PV panel open-circuit voltage; SGT process ensures high-frequency switching performance under MPPT perturbation, improving tracking efficiency. - **LED Lighting Drives (High Voltage Constant Current)**: Voltage margin handles inductive surges from LED strings; low switching losses reduce driver chip heating, suitable for long-life applications like industrial and street lighting. - **Electric Vehicle Chargers / Battery Charge and Discharge Management**: Suitable for 60V~120V battery pack architectures, used for secondary-side synchronous rectification in chargers or discharge circuit protection; wide safe operating area enhances robustness. - **Communication Base Station Power Supplies**: In narrow-frame, high-power-density module power supplies, the thinness of DFN8(3X3) packaging and the low gate charge advantage of SGT technology significantly improve heat dissipation and EMI.**Selection Summary**: The PML340SN,118-VB balances on-resistance, switching speed, and packaging thermal performance at the 200V withstand voltage level. It is a cost-effective, general-purpose choice for high-voltage, low-current switching applications, especially suitable for power supplies, industrial control, and new energy systems with strict requirements on board area, temperature rise, and conversion efficiency.
