T1440-VB MOSFET Product Introduction
T1440-VB is a high-voltage N-channel power MOSFET in TO251 package, designed for high-voltage switching applications. Its maximum drain-source voltage (V_DS) is 650V and the maximum drain current (I_D) is 2A, which is suitable for medium-power power management and switch control circuits. T1440-VB uses Plannar technology to provide lower on-resistance (R_DS(ON) = 4300mΩ @ V_GS = 10V), which can provide stable operating performance in higher voltage environments.
The threshold voltage (V_th) of this MOSFET is 3.5V, which is suitable for power circuits that require medium voltage control. T1440-VB is particularly suitable for applications that require high switching frequency and stable performance, such as power adapters, battery management systems, and low-power DC-DC converters.
