BSS123NH6327-VB Product details
Back to previous pageProduct introduction：
The BSS123NH6327-VB is a Single N-MOSFET meticulously optimized for high-voltage, low-power switching applications. Trench technology balances low losses and high reliability, while the SOT23-3 package achieves a good trade-off between thermal performance and board space. The combination of 100V voltage rating, 0.26A current capability, and 2.8Ω on-resistance makes it an ideal replacement for traditional high-voltage small-signal discrete devices, especially suitable for high-density, low-power applications.
