ME3902-VB Product details
Back to previous pageProduct introduction：
1. ME3902-VB Product Introduction: ME3902-VB is a **dual N-channel MOSFET** in a **SOT23-6 package**, designed for efficient power management and switching applications. The maximum drain-source voltage \(V_{DS}\) of this device is 20V, and the rated range of the gate-source voltage \(V_{GS}\) is ±12V, which is suitable for a variety of low-voltage power applications. Its threshold voltage \(V_{th}\) ranges from 0.5V to 1.5V, which means that it can be effectively turned on at a lower gate voltage. The on-resistance \(R_{DS(ON)}\) of ME3902-VB is 28mΩ and 22mΩ at gate voltages of 2.5V and 4.5V, respectively, showing excellent conductive performance. The maximum drain current \(I_D\) is 6A, which is suitable for applications with a variety of current loads. The use of **Trench technology** enables the MOSFET to have lower switching losses and efficient thermal management performance when switching.
