TF3N50-VB Product details
Back to previous pageProduct introduction：
Product Introduction
**TF3N50-VB** is a unipolar N-channel MOSFET in TO220F package, designed with Plannar technology, with a withstand voltage of 650V and a drain current (ID) of 4A. The on-resistance (RDS(ON)) of this MOSFET is 2560mΩ at VGS=10V. Compared with many low-voltage MOSFETs, its on-resistance is higher, so it is suitable for low-power and high-voltage applications. The threshold voltage (Vth) of TF3N50-VB is 3.5V, which is suitable for medium and high voltage switching applications. This MOSFET is widely used in equipment that requires higher voltage but lower current requirements, such as high-voltage power supplies, home appliances, power control systems, and small motor drives.
