FDU6780A-VB Product details
Back to previous pageProduct introduction：
Are you designing a high-power-density DC-DC module with tight board space but need to reliably handle over 40A of current? Ordinary MOSFETs either have high conduction losses or present thermal design challenges. The VBsemi FDU6780A-VB is designed for this exact purpose – it integrates a 30V withstand voltage, 50A current carrying capability, and an on-resistance of only 7mΩ into the TO251 through-hole package, making high-current power supply designs both efficient and reliable.
