Product Introduction
K2903-VB is a high-performance N-channel MOSFET in TO220F package, designed for high current and low on-resistance applications. Its drain-source voltage (VDS) is 60V, suitable for use in multiple electronic devices and can withstand higher voltages. In addition, the maximum drain current (ID) of this MOSFET can reach 70A, meeting the needs of high-power applications. Its threshold voltage (Vth) is 2.5V, which enables efficient conduction at a lower gate-source voltage. At gate-source voltages of 4.5V and 10V, its on-resistance (RDS(ON)) is 12mΩ and 10mΩ respectively, showing excellent electrical performance, suitable for demanding power management and drive circuits.
