BSS131H6327XTSA1-VB Product details
Back to previous pageProduct introduction：
BSS131H6327XTSA1-VB is a Single N-MOS deeply optimized for high-voltage, low-power switching scenarios. Trench technology balances low switching loss with high reliability, and the SOT23-3 package strikes a balance between heat dissipation and board space. The combination of 250V drain-source voltage, 0.3A continuous drain current, and 1500mΩ on-resistance makes it an ideal choice for high-voltage auxiliary power supplies, smart home appliance control, and industrial small-signal switching applications, especially suitable for space- and cost-sensitive high-density, high-volume projects.
