Back to previous pageProduct introduction：
1. **STB270N4F3-VB Product Introduction**
STB270N4F3-VB is a unipolar N-channel MOSFET designed based on Trench technology, packaged in TO263, optimized for high-power, high-efficiency power management systems. The product has a maximum drain-source voltage (VDS) of 40V, supports a gate voltage (VGS) of ±20V, and its threshold voltage (Vth) is 3V, which can ensure stable switching under higher voltage conditions. The on-resistance (RDS(ON)) of STB270N4F3-VB is extremely low. When VGS=10V, RDS(ON) is 2mΩ, which means that it has very low conduction losses under high current loads, thereby improving system efficiency and reducing heat generation. The maximum drain current (ID) is 150A, which is suitable for handling high current applications and can meet the needs of high power loads.
STB270N4F3-VB is widely used in many fields requiring high efficiency and high reliability, and is particularly suitable for power electronics, electric vehicles, power conversion and other systems, especially for applications with high requirements for low conduction loss and high current handling capabilities.
