Back to previous pageProduct introduction：
1. 9971-VB SOT223-3 Product Introduction
9971-VB is a single N-channel power MOSFET packaged in SOT223, designed for high-efficiency power management and conversion applications. Its advanced trench technology ensures low on-resistance and high switching speed, suitable for applications requiring high performance and high reliability. Its main features include a drain-source voltage (VDS) of 60V, a gate-source voltage (VGS) of ±20V, and a threshold voltage (Vth) of 1.7V. At a gate-source voltage of 4.5V, its on-resistance (RDS(ON)) is 33 milliohms, and at a gate-source voltage of 10V, the on-resistance is further reduced to 28 milliohms. The device is capable of carrying a current of 7A and is ideal for a variety of power and drive applications.
