SI7344DP-T1-GE3-VB Product details

Product introduction:

Product Introduction

**SI7344DP-T1-GE3-VB** is a single N-channel power MOSFET in a **DFN8(5X6)** package. It combines high current capability with low on-resistance and is particularly suitable for high-power power systems that require efficient switching performance. This MOSFET uses **Trench technology** to provide low switching losses, fast response and efficient power conversion, and is widely used in multiple low to medium voltage power management systems.

The maximum drain-source voltage (V_DS) of this MOSFET is **30V** and the maximum drain current (I_D) is **80A**, making it suitable for high current loads and low voltage applications such as **power converters, load switches, battery management systems**, etc. Its low **R_DS(on)** (9mΩ at V_GS=4.5V, 7mΩ at V_GS=10V) can effectively reduce power losses and improve overall efficiency, especially in high switching frequency environments, with lower heat losses.
