Product Introduction
SFT1440-E-VB is a unipolar N-channel MOSFET in TO252 package with high withstand voltage (650V) and low on-resistance, suitable for high voltage and high power electronic applications. The maximum drain-source voltage (V_DS) of this MOSFET is 650V, and the maximum gate-source voltage (V_GS) is ±30V, which can work stably at higher voltages. Its threshold voltage (V_th) is 3.5V, with good switching characteristics. The on-resistance of this device is 3440mΩ when V_GS is 4.5V and 4300mΩ when V_GS is 10V. It is suitable for power management, power control and switching applications with low current (maximum 2A) and certain requirements for on-resistance. SFT1440-E-VB adopts Plannar technology to ensure low power loss and good thermal stability, and is suitable for power switching applications that require high withstand voltage and low to medium current.
