PSMN4R2-80YSEX-VB Product details
Back to previous pageProduct introduction：
You are designing a high-power-density server power supply or automotive-grade DC-DC converter, facing 100V bus voltage and hundreds of amperes of current. Ordinary MOSFETs either lack sufficient voltage tolerance or suffer from excessive conduction losses, making thermal solutions a challenge. VBsemi PSMN4R2-80YSEX-VB is designed for exactly this—it uses an LFPAK56 package to achieve an on-resistance of just 3.0mΩ at 100V withstand voltage, supporting a continuous current of 180A, allowing high-power conversion systems to find the perfect balance between efficiency and reliability.
