2N7002-7-F-79-VB Product details
Back to previous pageProduct introduction：
2N7002-7-F-79-VB is a Single N-MOS optimized for low-voltage small signal switching scenarios, using Trench technology to combine low power consumption with high reliability. The SOT23-3 package strikes a good balance between thermal performance and board area. The combination of 60V withstand voltage, 0.3A current capacity, and 2.8Ω on-resistance makes it an ideal miniaturized alternative to traditional TO-92 or larger packaged devices, particularly suitable for high-density, low-power applications.
