NCE3N15D-VB Product details
Back to previous pageProduct introduction：
The NCE3N15D-VB is a Single N-MOS deeply optimized for high-voltage power switching scenarios. The Planar process balances high voltage withstand with robust reliability, and the TO263 package balances high-current heat dissipation with ease of installation. The combination of 1500V voltage withstand, 3A current capability, and 6500mΩ on-resistance makes it an ideal choice for replacing traditional high-voltage discrete devices in high-voltage auxiliary power supplies, industrial control, and new energy systems, especially for applications with stringent requirements for voltage margin and long-term stability.
