Back to previous pageProduct introduction：
1. STB85NF3LL-VB Product Introduction
STB85NF3LL-VB is a single N-channel power MOSFET in TO263 package with a maximum drain-source voltage (VDS) of 30V and a maximum drain current (ID) of up to 98A. This MOSFET uses Trench technology and has extremely low on-resistance (RDS(ON) = 2.7mΩ @ VGS = 4.5V, RDS(ON) = 2.4mΩ @ VGS = 10V), making it excellent in high-efficiency energy conversion and high-current applications. Its low on-resistance characteristic minimizes power loss during high-current and high-frequency operation, and is widely used in power management, battery drive, and applications requiring high-efficiency switching.
