BSS83IXUSA1-VB Product details
Back to previous pageProduct introduction：
BSS83IXUSA1-VB is a Single P-MOSFET deeply optimized for high-side switching and load management scenarios. The Trench process provides stable switching characteristics and good ESD reliability in low-current applications, with the SOT23-3 package achieving minimal footprint, suitable for high-density integration designs. The combination of 60V withstand voltage, -0.5A current capability, and 2Ω (10V drive) on-resistance makes it an ideal low-power option for portable devices, auxiliary power supplies, and battery management, especially for space-constrained, high-volume applications.
