Product introduction:

1. K4121LS-VB MOSFET Product Introduction

K4121LS-VB is a high-performance single N-channel MOSFET, designed with TO220F package, with good heat dissipation and electrical insulation characteristics. The drain-source voltage (VDS) of this MOSFET is 550V, which is suitable for high-voltage applications. Its gate-source voltage (VGS) can reach ±30V, ensuring stability under a variety of working conditions. The turn-on threshold voltage (Vth) is 3V, the on-resistance (RDS(ON)) is 260mΩ when VGS=10V, and the maximum drain current can reach 18A. K4121LS-VB adopts planar technology, which can effectively improve power conversion efficiency and is particularly suitable for high-voltage and high-power applications.
