Product introduction：
Product Introduction: RJK0349DSP-VB
RJK0349DSP-VB is a high-performance unipolar N-channel MOSFET in SOP8 package, designed for low-voltage and high-efficiency applications. The device has a maximum drain-source voltage (VDS) of 30V and can operate stably over a wide voltage range. Its threshold voltage (Vth) is 1.7V, which enables it to turn on quickly at a lower gate-source voltage, making it suitable for high-frequency switching applications. The on-resistance (RDS(ON)) of RJK0349DSP-VB is 4mΩ at VGS of 4.5V, and drops to 3mΩ at VGS of 10V. The extremely low on-resistance enables it to perform well in high-current applications, with a maximum drain current (ID) of up to 25A, providing excellent power handling capabilities.
