UF840L-VB Product Introduction

**UF840L-VB** is an **N-type MOSFET**, packaged in **TO220F**, designed for medium and high voltage power applications. Its **drain-source voltage (VDS)** is as high as **650V**, which can work stably in high voltage occasions and is suitable for various high voltage power supplies and switching circuits. This MOSFET has a maximum **drain current (ID)** of **12A**, and adopts **Plannar technology** to provide a moderate on-resistance **RDS(ON) = 680mΩ** @ **VGS = 10V**, enabling it to maintain good power efficiency in high voltage and medium current applications. Its **gate-source threshold voltage (Vth)** is **3.5V**, which supports a wide operating gate-source voltage range and has low switching losses. UF840L-VB is particularly suitable for application scenarios that require high voltage resistance and large current carrying capacity, such as power conversion, switch mode power supply (SMPS) and industrial control systems.
