1. Product Introduction
**STS3622-VB** is a dual N-Channel MOSFET in a SOT23-6 package, suitable for low-voltage and high-efficiency switching applications. Its maximum drain-source voltage (V_DS) is 20V, and its maximum drain current (I_D) is 6A. It uses Trench technology to effectively reduce on-resistance and improve switching performance. This model has a threshold voltage (V_th) in the range of 0.5V to 1.5V, which enables fast switching at a lower gate voltage, making it suitable for a variety of low-power, high-frequency electronic devices. Its on-resistance (R_DS(ON)) at 2.5V and 4.5V gate voltages is 28mΩ and 22mΩ respectively, ensuring the lowest power consumption under efficient current control.
This MOSFET is particularly suitable for applications that require efficient power management, fast switching and low-power control, such as small electronic devices, communication modules, and electric drive systems.
