Product introduction：
RJK0226DNS-WS#J5-VB is a Single N-MOS deeply optimized for low-voltage high-current power switching scenarios. The Trench process balances extremely low conduction losses with fast switching characteristics, and the DFN8(3X3) package achieves an excellent balance between compact footprint and superior heat dissipation capability. The combination of 20V voltage rating, 100A current carrying capability, and 2mΩ-level on-resistance makes it an ideal core device for high-density power modules, battery protection, and motor drive applications, especially suitable for projects with strict requirements on efficiency and temperature rise.

- VDS=20V: Suitable for 5V/12V low-voltage systems, providing ample margin for switching node spikes, improving circuit reliability.
- VGS=±12V: Compatible with 2.5V~12V drive voltages, flexibly works with MCU/PMIC or dedicated gate drive circuits.
- Vth=0.6V (Typical): Ultra-low threshold voltage, supports direct drive from low-voltage logic, ensures full conduction even during battery voltage droop.
- RDS(on)=2.5mΩ @ VGS=4.5V, 2mΩ @ VGS=10V: Ultra-low on-resistance significantly reduces full-load conduction losses and thermal design requirements.
- ID=100A: Ample continuous current capability to handle surge currents and sustained output demands of high-power loads.
- Package DFN8(3X3): Ultra-small package with bottom-side thermal pad, balancing low parasitic inductance and efficient heat transfer, ideal for high-power-density designs.
Domain and module applications：
- Battery Protection Module: Extremely low internal resistance reduces protection board self-heating; 100A high current capability meets power battery and energy storage system requirements; fast response ensures overcurrent/short circuit safety.
- DC-DC Converter: Replaces traditional Schottky diodes in synchronous rectification applications, significantly improving heavy-load efficiency, aiding power module miniaturization and high density.
- Low-Voltage Motor Drive: Low PWM switching loss, low conduction voltage drop, smooth motor operation, significantly reduced driver temperature rise, suitable for power tools, fans, and other equipment.
- Power Tools and Portable Devices: High current carrying capacity combined with small package, suitable for high-power power tools, drones, and fast charging/boost circuits for power banks.
- Load Switch: Milliohm-level on-resistance makes system voltage drop negligible, suitable for hot-swap, power path management, and high current load on/off control.
- Automotive Auxiliary System: 20V voltage withstand and 100A current capability adapt to automotive low-voltage buses (e.g., 12V systems); low loss improves energy utilization efficiency. Selection Summary: RJK0226DNS-WS#J5-VB achieves an excellent balance between ultra-low on-resistance, high current carrying capacity, and compact packaging. It is a high-performance first choice for 20V low-voltage, high-current switching applications, especially suitable for power and motor control projects with extreme requirements for space, efficiency, and thermal management.
