CSD19537Q3T-VB Product details
Back to previous pageProduct introduction：
** Are you designing a high-power-density industrial power supply or a brushless DC motor drive that needs to withstand current surges up to 50A while controlling heat generation in a limited space? Ordinary MOSFETs either lack sufficient voltage tolerance or have high on-resistance, compromising system efficiency and reliability. The VBsemi CSD19537Q3T-VB is designed for exactly this purpose – based on advanced SGT technology, it integrates 100V withstand voltage, 50A continuous current capability, and a low on-resistance of 10.5mΩ into a compact DFN8(3X3) package, allowing high-voltage, high-current designs without compromise.**
