SI7804DN-T1-E3-VB Product details
Back to previous pageProduct introduction：
You are designing a high-power-density DC-DC converter. Board space is tight, yet it must reliably handle 30A of current. Traditional MOSFETs are either too large in package or suffer from high conduction losses. The VBsemi SI7804DN-T1-E3-VB is designed for this exact purpose – it integrates 30V withstand voltage, 30A current carrying capacity, and an ultra-low on-resistance of 13mΩ into the compact DFN8(3X3) package, freeing high-current power supply designs from the constraints of heat dissipation and space.
