NTD4906N-35H-VB Product details
Back to previous pageProduct introduction：
The NTD4906N-35H-VB is a Single N-MOS deeply optimized for low-voltage, high-power switching applications. The Trench technology achieves a good balance between ultra-low on-resistance and fast switching capability. The TO251 package combines heat dissipation performance with through-hole mounting reliability. The combination of 30V withstand voltage, 100A current carrying capacity, and 3.5mΩ on-resistance makes it an ideal choice for low-voltage, high-current power paths, battery protection, and motor drive applications, especially for systems with stringent requirements for conduction loss and thermal performance.

VDS=30V: Suitable for 5V/12V/24V systems, providing ample margin for switching spikes to improve transient reliability.
VGS=±20V: Compatible with 4.5V~12V logic level drive, can directly connect to controllers or drivers, simplifying gate circuit design.
Vth=1.7V (typical): Effectively turns on under low-voltage drive, balancing low-voltage logic compatibility and noise immunity.
RDS(on)=3.5mΩ @ VGS=10V, 4.5mΩ @ VGS=4.5V: Ultra-low on-resistance significantly reduces full-load conduction loss, optimizes thermal design, and supports continuous high current output.
ID=100A: Ample continuous current capability to meet peak demands of high-power density modules and heavy-load scenarios like power tools.
Package TO251: Through-hole mounting offers high mechanical strength, metal backplate provides a short heat dissipation path with low thermal resistance, suitable for medium-to-high power PCB layouts.
Domain and module applications：
Low-voltage high-current switching circuits: Extremely low on-resistance significantly reduces full-load voltage drop and temperature rise, improving overall system efficiency.
Battery protection and BMS: Milliohm-level internal resistance reduces self-heating of the protection board, and high-current switching capability is suitable for power batteries and energy storage systems.
DC-DC converters and synchronous rectification: Replaces high-loss Schottky diodes, significantly improving heavy-load efficiency and facilitating module miniaturization.
Low-voltage motor drives: Low PWM switching losses, smooth motor operation, and significantly reduced thermal stress on the controller.
Power path management: Supports high-current load switching, and bidirectional conduction characteristics are suitable for Oring circuits and load switches.
Automotive auxiliary systems: 30V voltage margin combined with the good heat dissipation capability of TO251 is suitable for 12V/24V automotive bus environments.
Power tools and industrial control: High current margin and low on-resistance meet surge load requirements, improving equipment reliability.
Selection Summary: The NTD4906N-35H-VB achieves an excellent balance between ultra-low on-resistance, high current carrying capacity, and package heat dissipation performance. It is a high-performance general-purpose choice for 30V low-voltage, high-power switching applications, especially suitable for projects with strict requirements for current handling and thermal dissipation.
