BSS84IXUSA1-VB Product details
Back to previous pageProduct introduction：
BSS84IXUSA1-VB is a Single P-MOS deeply optimized for low-voltage power switching scenarios. Trench technology balances low switching loss and high reliability, while the SOT23-3 package strikes a balance between heat dissipation and footprint. The combination of 60V withstand voltage, 0.5A current capacity, and 3000mΩ on-resistance makes it an ideal cost-reduction and incremental option for replacing traditional SOT-23 or SOT-89 packaged devices, especially suitable for high-density, high-volume applications.
