NTD70N03R-1-VB Product details
Back to previous pageProduct introduction：
Imagine: You are designing a high-power-density DC-DC converter with tight board space but needing to handle nearly a hundred amperes of peak current. Ordinary MOS tubes either have excessive conduction losses or insufficient package heat dissipation. VBsemi NTD70N03R-1-VB is designed for this—it integrates 20V withstand voltage, 100A current-carrying capacity, and an on-resistance as low as 4.5mΩ in a standard TO252 package, allowing high-current power supply design to proceed calmly without compromising between performance and size.
