BSS138NH6327XTSA2-VB Product details
Back to previous pageProduct introduction：
The BSS138NH6327XTSA2-VB is a Single N-MOSFET deeply optimized for low-voltage small-signal switching applications. The Trench process balances low power consumption with high reliability, and the SOT23-3 package strikes a good balance between heat dissipation and footprint area. The combination of 60V withstand voltage, 0.3A current capability, and 2.8Ω on-resistance makes it an ideal, cost-effective choice for signal level shifting, load switching, and driver circuits, especially suitable for high-density, low-power, high-volume applications.
