TK40A08K3-VB MOSFET Product Introduction
TK40A08K3-VB is a unipolar N-channel power MOSFET in TO220F package with a drain-source voltage (VDS) of up to 650V and a gate-source voltage (VGS) of ±30V. This MOSFET has a threshold voltage of 3.5V and uses planar technology (Plannar), which is suitable for medium and low power power conversion and switching control applications. Although the on-resistance (RDS(ON)) is relatively high (2560mΩ@VGS=10V), it performs well in low current (such as 4A) and medium voltage environments, and is particularly suitable for scenarios that require stable switching performance and voltage resistance. It is widely used in low-power applications such as power adapters, LED drive circuits, household appliances and other fields.
