2N7002KX-7-VB Product details
Back to previous pageProduct introduction：
2N7002KX-7-VB is a Single N-MOS optimized for low-voltage, low-power switching scenarios. The Trench process balances low conduction losses with high reliability, and the SOT23-3 package strikes a balance between heat dissipation and board area. The combination of 60V withstand voltage, 0.3A current capacity, and 2.8Ω (typical) on-resistance makes it an ideal choice for logic-level driving, signal switching, and small power load control, especially suitable for high-density, high-volume applications.
