Back to previous pageProduct introduction：
Product Introduction:
**UF840-VB** is a high-voltage, high-current handling N-channel MOSFET in TO220F package based on Plannar technology. This MOSFET has a drain-source voltage (V_DS) of 650V, which is suitable for high-voltage applications. Its threshold voltage (V_th) is 3.5V, and the gate-source voltage (V_GS) can reach a maximum of ±30V, which can adapt to a variety of working conditions. The on-resistance (R_DS(ON)) is 680mΩ@V_GS=10V, and the drain current (I_D) is 12A, with good current carrying capacity and relatively low conduction loss. UF840-VB is widely used in high-power power conversion, power management, industrial control and other fields, and is an ideal choice for handling high voltage and high current loads.
