PSMN2R8-40BS,118-VB Product details
Back to previous pageProduct introduction：
VBsemi PSMN2R8-40BS,118-VB is a Single N-channel power field-effect transistor using Trench technology, designed for low-voltage, high-current power conversion and high-power-density control scenarios. Its TO263 package offers excellent heat dissipation capability and current carrying capacity, suitable for applications such as power supplies, motor drives, and battery protection that require high reliability. The device provides extremely low on-resistance within a 40V drain-source voltage range (typical value only 2mΩ at 10V gate voltage), significantly reducing conduction losses and improving system efficiency. Additionally, the gate drive is compatible with common logic levels, facilitating direct drive by controllers or driver chips, simplifying circuit design.
